Why does everyone on here assume that white people are racist towards black people?

Everyone on Answers.com or even throughout the world does not assume white people in general are racist towards all black people.

One may run into questions asking generalized statements but that does not represent the whole of a community no more than questions asking why black people are animals or why Jewish people are greedy.

That there are racist people who ask these questions does not mean everyone agrees with them and to think so is only another form of generalization.
