This one bothers me the most. Yeah, dating a black person doesn't automatically give you a free pass from racism, but the way these people use accusations of racism to manipulate others makes this whole piece one big ad for emotionally abusive mixed-race relationships, as if this is a healthy way to interact with your significant other!!
"Yeah, you're a honky, so even though you yourself aren't racist, I'm gonna go ahead and blame you for the actions of every other white person since the dawn of time, because clearly you benefit from the top 1% of white people in the US owning slaves 155 years ago. AND if you feel bad about being blamed for everything and want any emotional support from me, your significant other, that just means YOU'RE being the abusive one, even though I've clearly driven you to tears after you've apologized for your non-offenses. No I've never heard of gaslighting/narcissistic personality disorder, what are you talking about??"
