I doubt that me trying to write from the point of view of a minority character is going to be as accurate or authentic as a person in that minority group doing so.
Perhaps. It depends on if you feel there is a such a thing as an essential minority experience. What you probably can't do if you are a white person from rural Minnesota is write with the immediatecy and depth of experience about a black character from Brooklyn as you could if you really were a black person from Brooklyn. There might indeed be shared experiences and voice you'd have being a minority in Brooklyn that weren't immediately obvious to someone who was from rural Minnesota. Your voice wouldn't be authentic because it wasn't. But notice how very different this claim is than the one I'm supposed to make.
1) It doesn't claim that there is an essential common "black" experience. It doesn't put an entire group of people in a single box which quite notably, we get to put the label on and decide what is "authentic" (or if not us, then the racial spokesperson we appoint). The ultimate end of that sort of thinking is to say that black criminals are authentic real blacks, but a black entrepreneur or a black suburbanite gamer nerd is not an authentic blacks. And you do hear lots of racists saying that, from the cultural studies professors that claim that those aren't authentic voices, the political pundits that call black politicians 'Uncle Toms' and 'House Slaves' if their beliefs don't conform to what they consider 'authentic' black beliefs, to the kids that would pass my table in high school and sneer at my friends for being 'oreos' and trying to be 'too white' as if it wasn't authentic for a black person to love books, do their homework, try to stay out of trouble, and generally be anything but a criminal.
2) It's not an absolute claim. I'm not claiming a writer can't imagine lives other than their own nor discouraging people to try.
3) It's not a racist claim. I'm not claiming that the reason a person can't write authentically about another person is skin color. The writer from rural Minnesota would have just as hard of a time writing in an authentic voice about authentic experiences of anyone from Brooklyn regardless of face. The black writer in Brooklyn likewise might well have a hard time speaking in the voice of a black family living in rural Minnesota. Indeed, we might expect that the writer in rural Minnesota could conceive either from personal experience or extrapolation better what that situation might be like and how his community would react - positively or negatively I can't imagine because I didn't grow up in rural Minnesota.
4) It's not a double standard: Did you notice how this point is only raised in one direction? Whenever it comes up, it's invariably about the inability of white people to write minority characters. But the same standard being raised doesn't claim that black people can't write authentic white characters. That standard says that privilege (a word twisted often so badly to Newspeak style mean its opposite) prevents whites from speaking of minorities, but minorities can speak of whites authentically. That double standard isn't the only reason that the idea promotes hatred - I mean it's racism, so it tends to promote hatred period - but it's a big part of it.
Granted if I am a racist who uses that characterization to present them negatively or if I am just grossly insensitive, that warrants criticism.
I half agree, but you really have to be careful there. Because when you remove tolerance and understanding from the equation here, the way that tends to be interpreted - and the way it is continually interpreted in our present society - is that it is ok to portray "minorities" if you portray them in a completely positive fashion. And what that tends to mean is that it's only ok to portray minorities as fully positive characters without significant flaws because to show a minority character as flawed is racist. Likewise what it tends to mean is that if you are doing comedy of some sort, the person doing the broad comedy has to be a white male. But I put it to you that this isn't exactly a big step forward. What it tends to mean is that we've gone from a society where in situation comedy, the broad comedy is done by a bimbo character ("I Love Lucy" being an interesting example on several levels) to a situation where every situation comedy has a 'himbo' father figure. We aren't actually attacking stereotypes or creating more real characters. We are just creating new stereotypes. That's not progress. And even wholly positive stereotypes can be damaging, because they create the impression not only of falsehood, but that any person of that race that doesn't live up to high standard has something wrong and threatening about them. You tend to end up in a situation where a person without a lot of multiracial experience who sees anyone that doesn't look like a Huxtable thinks that they must be a dangerous thug or in some other way anti-social.
You mention Kipling later, a writer that tends to send the cultural studies people into fits because he decidedly doesn't create singularly positive romantic views of other groups nor condemn his own group as uniformly devils. But close reading of the guy shows he's a lot more subversive than people used to only seeing "minorities" (as if Hindu's in India were a minority group) presented in entirely flattering ways. He's actually repeatedly attacking the assumptions of his own culture. His heroes tend to sit astride both worlds - Kim across England and India or Mowgli between civilization and the jungle or Sir Purun Das between Western and Eastern philosophy - and ultimately not only do they tend to choose to forsake Englishness, but Kipling vindicates them for it as choosing the better part. He's often explicitly attacking the values and even political policies of his own nation. He deserves a nuanced reading. But he doesn't get one because he's decidedly not 'politically correct'. He doesn't uniformly condemn England. He doesn't uniformly praise India.
My other worry here is it feels like we are creating this gulf where we can't ever truly know each other.
The whole theory proceeds from the idea that there is this gulf where we can't ever truly know each other. That's one of its bedrock beliefs. No one can "walk a mile in another's shoes". No one can empathize enough to understand. No one has common experience. No one can speak to another's situation. All you can do is confess your inability to know and understand and shut up (and take direction from the self-appointed "authentic" voices). Separating and dividing is what it is all about. It's the same group of idiots - black and white - that were always insulting my friends for being "oreos" or "zebras" because they were trying to be "white" (whatever the hell that means) promoting this damnable idea.
Another concern I have is, this seems to really kind of be about sophistication.
No. No. No. Just no. I mean it is a sophistication, but its not that getting the right sort of education makes you immune and allows your privilege and education to see more clearly than the ignorant racist country bumpkins. That's what they'd like you to believe, but notice how self-serving and how classist that ultimately is. They'd like to give the 2%er's in the Hamptons or in the academic Ivory Towers the privilege to ignore this once they've kowtowed and performed their religious absolutions because they are the 2%er's. Of course they want the privilege to ignore their own rules. But even without getting into a rant about how so many that think they are educated don't have a real education, nothing about having lived in the ivory tower gives you any kind of authentic understanding of anything except living in the ivory tower. Believe me, I've been in academia. Got the published papers to prove it. It's filled with just as many ignorant idiots as any dusty warehouse I've ever swept. Education is no defense against normal human stupidity, and to the extent that it inculcates arrogance its arguably a wide open temptation to stupidity and not a bulwark. I trust your average construction worker to have a more nuanced understanding of race and race relations than your average academic, because he has to make his theories work for him on a daily basis. It isn't proof against racism, and indeed sometimes it creates a daily friction and chaffing that shows up in racist frustration by all parties involved, but by golly it's real and not a fantasy.
You sir shouldn't back down in the slightest from some racial essentialist whose biggest encounters with people of a different race are on TV as if they understood race. 90% of these white knights are the sort that are all publically social justice, but privately are like "This black family moved just a 1/2 mile from here. I'm afraid we are going to have to sell the house. Not racist of course, just property values you understand" And no, those quotes aren't made up or hypothetical.
