I honestly think MOST Republicans are solid, upstanding citizens who would be appalled to be called racists. The problem is that Trump's base have been so conditioned (by Fox, for instance) to fear ....well, everything. I've read a lot of psychoanalysis regarding the kind of people who gravitate toward authoritarianism and the qualities that Trump displays. They had a strong father figure, etc. It's been proven with brain scans that conservatives react more strongly to fear than liberals do. Almost every day Fox plays to that fear. I think Fox and right wing radio have a lot to answer for with regard to the upsets that are tearing the country apart right now.
