Why do so many black american women have a victim mentality?

Why do so many Black American women still complain so much about racism? I get so tired of their complaining attitude.

Don't get me wrong: racism exists, and it may be worse in the US than it is here in the Netherlands. I don't know. But go file a complaint, go to the police, or whatever authority is appropriate. If you're a victim of something, your identity is not "victim." So why does their entire identity become that of a complaining woman who feels like she never has the same rights and is always being mistreated?
