You have to do what comes naturally to you. Be who you are. Discern yourself with "history's" truimphs and failures. You don't have to feel like you have a heavy load to carry. Be you. People are going to be a-holes regardless. If you show love the love, will come back. If you show hate the hate comes back. It's that simple. I can't tell you about growing up with a black and white parent. But I can tell you about learning to understand you.
Asking questions are great. But asking the question of your innerself is greater. Go with what you know best. There are good and bad on both sides of the "races". If you are trusting of yourself you will find people you can trust. And that's all that matters in the long run. That you are able to live you life, so YOU can get most out of it.
Cut down on the drama and simplify things. (Just a general statement, not directed to you per se.)
