I assume by "our society" you mean "white society". I agree that it's sad that black people seem to have such a low opinion of themselves but since when is it the white peoples job to make black people feel good about themselves? If anything I think they have failed themselves.
I am proud of my German roots. I'm also proud that those roots were smart enough to get out before the crazies took over. If people with African roots aren't proud of those roots thats just not my fault.
