This. They attack each other and other races too. Look at some of the Asian communities on the West Coast.

It's the hip hop culture. The youth think it's cool to be gansta. They do stupid shit to get street credit and be cool. Of course this leads to them getting arrested eventually which makes it difficult to get a job. Most are probably unhirable anyway because they can't speak proper english, dress like a gangsta, or are covered in tats. Since they can't get jobs they become more gansta.

Eventually they grow up a little and realize they don't want to be ganstas all their lives. They look around and see other people working and blame them for their troubles. The youth take this view too and take out their anger on other races mostly whites because "the man" is considered white. Of course they don't realize they are doing this all to themselves though their hip hop culture.

If you were the leader of the KKK and wanted to come up with a plan to keep blacks down, the hip hop culture would be a great plan. It's a vicious cycle. They get caught in this trap when they are too young to realize it.

The leaders of the black community are the ones who need to steer their community in different directions. Obviously they aren't and many even embrace this culture.

TLDR: They are attacking Whites and other races because they blame their problems (which 90% are their own fault) on other races who they think are out to get them.
