I hate the "they do it on both sides" fallacy, because it doesn't see severity. For example, let's say I say "White people sure do use a lot of drugs!" Nobody is going to not hire a white person for a job simply because they use more drugs than other groups of people. It takes a whole society working together to create racism, it's not all about individual opinion. We have the media constantly flogging "blacks have a pathological culture"(common ones: blacks don't want to succeed in school, blacks listen to all that rap music and thus are criminals) or "Black people are hysterical liars" and suchlike. We have the government not really doing much about black problems- like if they have the money to bomb another country, why can't our schools get some teachers who can teach? We have disparate police presence in our neighborhoods and yea, we do have some employers endorsing racism stereotypes.
So when a white person says "Black people sure do use a lot of drugs!" they are keeping the lies that that huge system going. If the public doesn't believe that we need to be doing something about all these drug dealing Negroes, harsh laws aren't passed. If the chief of police doesn't believe that black neighborhoods or black people need 'special' service, then the harassment and brutality goes away. If the teacher believes black kids want to learn, they teach better, and so on. Of course, there is more to it than that, but having a power analysis and refusing to spread or believe things like that can help a bit.
That's why I'm a pro black black person. A pro black black person doesn't go around always hating on their own people, and moralizing(both destructive) but seeks constructive solutions to the problems caused by the system of our country.
