I just found out my brother-in-law is a racial separatist. I knew he was a big Trump supporter but didn’t know why. As it turns out, he sees supporting Trump as the best way to avoid the “inevitable race war” that will occur when whites are no longer a numerical majority. He argues that history proves the races cannot peacefully coexist and is “interested” in whether all races have the same IQ. I love my wife’s family and spend a lot of time with them. How do I move forward?
