The most insidious forms of racism are the ones we cannot see. Sure, your next door neighbor cracks racist jokes, but he's basically just a jerk. The dangerous racists are the ones who hold political power and have the ability to oppress people on a large scale - by gerrymandering, deciding what shouldn't be taught in schools, ending social welfare programs etc. And Trump is a perfect example of a bigot with Black friends and a Jewish son-in-law.
