There's a lot of sense to what you're saying. Quite fair arguments. But the reason why some PoC (in contrast to the ability you speak of in your meme) do not pick up this ability, is because they are still suffering from racism since they day they were born. If you're born into it, how can you know that what you face is wrong? Only as you grow older and see the differences, are exposed to different cultures within your own country, are you able to see the racism.
It's ironic that you speak of joining a parade instead of fussing. I remember when I was taking care of the elderly who likes to watch Fox News, there was Tucker Carlson talking about how it is unfair to have support groups for people of color to have support groups for racism and prejudice based on the color of their skin. He asked, why don't whites get such a support group. Stunned by the audacity of the question, the man couldn't answer. The moment he was able to start to come up with one, Tucker recognized it and cut him off in the interview.
Sure, it's a fair argument on paper. But the reality is that if you face racism as a white person in the school where this took place, you might be the only one who shows up once for a whole year. You'd rather divert a budget to have something that no one shows up to?
Then there's the whole thing where Trump said diversity training was anti-white propaganda. Which was the most blatant act of racism to date, right up there with telling the squad to go back to their countries. Diversity training isn't anti-white propaganda. It's a program designed to teach people how to work together with people from different walks of life, reconcile differences, etc.
I mean, I get it, there is racism against whites. I'm not denying that. But, in light of our past, and in light of our actions today, even. .... We gotta have a few good years where we turn the other cheek. I mean, that's the Christian thing to do, right? Isn't the majority of Trump supporters Christian?
