first: right wings ask the same question of left wings. both have opposing view points yet ask the same questions about each other. when it comes to racism, there are racists on both sides, and both handle it differently. right wingers believe that left wingers are SUPER racist who lack self awareness but dont see themselves as remotely racist. i know people wont like that but that is what it is.
second: calling anyone a racist is a personal attack when you dont have proof. freedom of speech covers racist comments no matter how much it sucks. right wingers (much like left wingers) understand and are aware of what racism is and honestly disagree that their valid beliefs and policies are NOT racist. Especially Trump supporters who vary in all aspects, parties, race, etc.
so that question leads no where but to where it came from, because the only way to answer it is to asked that about yourself. and maybe later to understand that race is only a social construct. and that TRUMP and his supporters are HUMAN like you and me. they are only human no matter how much you or anyone else hates them.
