So you agree that harassment is a problem and worthy of discussion, but not as much of a problem or worthy of discussion as one woman's tone and phrasing? I'm sorry, but that is the textbook definition of missing the point.
A real ally doesn't disrupt a conversation about a systemic problem like harassment to declare personal umbrage at one individual's use of identity politics terminology. A real ally doesn't condescend about the person's "lack of maturity" even when they disagree with particular parts of their analysis, or if they think a certain sort of person might take it personally. A real ally wouldn't take it personally, because a real ally understands that it's not about them. A real ally understands a person can only put up with this crap for so long before needing to just f'in rant about it. A real ally understands that sometimes a person's just got to speak their own God damn truth.
What gets missed in this is that a post on a personal blog does not constitute outreach to a skeptical community. It is many ways preaching to a choir, and yes yes efficacy and impact yadda yadda, again, not the freaking point. Yes it ends in a call to action, but again a call to action to her followers, who are presumably on board with her analysis in the first place.
Would she have toned down her rhetoric, used more accessible language, if she were directly addressing and attempting to gain the buy-in of the gaming community? My guess would be probably. That's kind of what the folks in this thread have been attempting, with admittedly varying degrees of success (myself included). It's a hard topic not to get passionate about, which is frustrating when the opposition confuses passion with immaturity.
At the end of the day though, this thread isn't about one woman's one blog post leading a sole crusade against harassment in gaming. This thread, as both the title and Fearless Leader suggest, is about Harassment in Gaming.
