Or more to the point... the game and most of the players weren't
intending to be racist.
But because cultural mores change over time... parts of the game and some of the attitudes of the OSR/Old D&D might now be
considered racist at this point in time.
So if you are a part of the OSR/Old D&D and that matters to you... that parts of the game you enjoy have undertones of racism... all you need to do is to see what people are talking about when it comes to racism in OSR/Old D&D and choose to change the bits in your game and your attitudes towards them that could be considered racist without getting bent out of shape over it.
Of course we know that's hard... heck, people here on the boards get bent out of shape by rules changes or additions all the time even without ones with any racial undertones. And our defense mechanisms and hackles immediately jump up when any potential racism is implied. But really, what's worse? Pretending that the rest of society just doesn't "get it" and going about your business the same as you ever did... or acknowledging the potential and making small changes along the way just to keep yourself in check?
I know for me personally... I'm always seeing things in media that someone is decrying as -ist or an -ism and I sigh heavily and think "Really? You're getting upset about
that, now?!?" But then I take a moment to just think whether whatever that is is actually any kind of a big deal that impacts my life in any way shape or form and I realize that no it doesn't. So going along with the idea is no skin off my back if others believe it to be important in making more people happy.
And while I know there's a lot of folks desperately afraid of the whole "slippery slope" argument where they think society's going to break off and sink into the ocean if we "allow" this change to our mores to occur... trying to bring it to a screeching halt is rather pointless. Because the people pushing for these changes to our societal mores are usually younger than you and will outlive you. So you can try and fight the changes all you want, but eventually you're gonna die and the younger people will be able to keep those changes in place without you there to cockblock them anymore. So why make yourself miserable for the few years remaining in your life by trying to swim against the current and trying to prove to the young folks that this thing they believe is all wrong and they're going to hell if they continue it?
