I grew up around a lot of racists. As a kid, I heard the hard-r n-word on a weekly, if not daily, basis. I recognize racism when I see it.
And that post I quoted is straight out of the “Why Whites Are The Real Victims” chapter of the The Racist Handbook. It’s so stupidly over the top that it can’t possibly make a real point, instead it’s just a “whites are being mistreated” whine. It’s an attempt to not have to look at or address real racism but attempting to make whites the victim of being held to any kind of standard.
Again, you don’t want to be considered racist? Don’t say racist shit. And definitely don’t double down when called out on it.
