Why do whites spend so much of their time focusing on blacks?

Excellent question the racist whites on C&G who constantly ask questions about black people are ignorant, bored, and insecure idiots who feel the need to belittle others to feel better about themselves now while I'm not saying their aren't black trolls too because obviously there are quite a few it's just with white it's a more common thing and that's why in some of my answers I'll come down hard on whites not because I'm racist but because I am tired of people on here bashing black people and putting a whole group of people in to a category
