Trump is scary for many reasons. The liberals see him as scary because he is a racist. I do nto think that is true. I think Trump does not care about racism. He foments it, uses it, whether it is white or black.
This guy, Umar Johnson, is not different than one of Trumps hooded KKK supporters. While Trump is not going to get Johnson’s vote, the wink wink racism of the Trump campaign feed Johnson’s paranoia as much as it does the paranoid fantasies of David Duke.
