It's comments like this that perpetuate the notion that white people are bad for not wanting to hear any whining about the "horrible things done to others in the past by white people."
Black people should be grateful that they're here in this country. Black people have a better existence here and western Europe than anywhere else in the world.
Do we get a thank you? No, we don't want or expect one. But we don't think the "fuck you" given to us is fair either.
You're not owed anything because your ancestors were slaves. I have ancestors that were slaves also, everyone does.
You're not owed anything for having different water fountains and schools.
If you ever were owed anything it has been paid to you by getting to live here.
You shouldn't thank me or whites for living in america, but you should thank your lucky stars.
