If you consider abortion then America is probably worse now than in the slavery days but liberal Dem leaders like Clinton and Obama support that. They often put abortion clinics in black neighborhoods. White people sometimes get asked to leave. It basically happened to me a few weeks ago and I left but I do think the situation could and should have been handled differently.
There is a crime problem in the black community and it seems like there is a different attitude to thugs in the black community. If police shoot a white thug white people will often celebrate.
Have you considered running for public office? You could also help get people like me elected so black people don't bleed out on the street while the ambulance watches down the street because they have to wait on the police to show up. A lot of politics is local. Trump and Obama can't do much about bad local leadership whether it be in the black or white community.
