A whole bunch of white people fought a large-scale war over slavely. In the end, many white people died. I didn't do it myself, because I wasn't around back then, so I'm not going to take any credit. But this means I am also not going to take any flack for anything that happened before my time either.
What you should really do is learn exactly who it is that you should be mad at. You may have to dig a little bit, the media will not help you with this one. White people are not your enemy. Not even close. It's way more complicated than black vs white. Hopefully everybody will discover the truth. It is the one thing that will truly set you free.
