Why are people so obnoxious?

Theres always a question or answer here saying "I don't like black people, they are so unnatractive with their big noses" if sum of you idiots aren't smart enough to realize, just because the blacks that you've seen are unattractive, ghetto, or loud with big noses that doesn't meen all of them are. I've met alot of cute darker skinned girls with pointy noses, manners, small lips and all of that other crap that you bigots go on about, and whats with the "blacks should go back to africa" crap? did you guys know that America was actually the native americans land first? yea not the whites. I'm not discriminating, or trying to be rude, i don't even see colour man i love whites blacks yellows and purples.
