How do I deal with my ignorant boyfriend?

During one of our conversations I asked if he would ever date a white woman and he replied "no, I hate them"! So I ask, white women? And he replies white people in general! As the conversation went on he kept talking about how white people made it hard for us back in the day and treated us like dogs. How flicking off a man who has a confederate flag on his truck made him feel good, a bunch of non-sense! Then he started talking about me how I dont know my history and what I do know is a lie! " The white man got you!" What does that mean? He's 22 and I kept telling him that he's got a lot to learn! I know my history. I know that they're people in the world that still dont like black people. But why do I have to hate them just because they hate me?
