Because a white person that likes a black person just means he LIKES THAT INDIVIDUAL BLACK PERSON.
This is stupid. The bar for a racist is set at LIKING ALL Black people? I don't even like 1/2 the white people on the planet.
Clearly, for any critical thinking person, it's hard to be a racist if your fishing buddy is black. Ask Huckleberry Finn who has a race "awakening" that EVERY school child used to read about because of adventures with Jim.
That story proved to be too "problematic" for the leftists involved in our schools, because should the kids REMEMBER this story --- THEY might not need the Demo party to badger them about being racists and just make the effort to "explore" on their own. So they replaced it with a lot of literal gang-banging and novels that kids could closer identify with based on real problems like surviving gang warfare and having a crack whore lesbian mom.
What the OP is trying to tell you -- is that people are not won over by badgering them, as you prefer to do. People lose their prejudice and fear by direct associations. You lose that prejudice pretty quickly with a small number of associations. Like your black doctor or kid's teacher or your fishing buddy that owns the better bass boat.. LOL... .
