I've learned my lesson the hard way too. even in spite of me knowing how white people get down, I've STILL made friends with them, only to have them prove me right. I consider them good friends because they've taken time to help me out if I needed it and I will always appreciate that, I won't come here and pretend like I haven't had good experiences with white people, there are many other Black people here on the coli that have probably had excellent interactions with white people, but that doesn't change the fact they are inherently evil.
challenge their privilege and you'll see their true nature surface, much in the same way whites all around the country complain about Immigrants and them feeling like they're "losing the country", or the study that determined that white people feel they suffer more discrimination than Blacks in America, these aren't necessarily racist white folks who feel like this, but once their privilege and sense of entitlement is threatened they show their true nature.
