If we're being fair here, even mentioning you're conservative tends to have people call you racist regardless of issue. It went from people just calling you an asshole to just a racist bigot. That is obviously in large part thanks to Trump.
Well, if the leader of the party calls for white nationalism, supports Nazis, enacts anti-LGBT laws, is now putting up anti-woman candidates, and puts children into cages, then one has two options.
1. Outspoken criticism, not supporting the dear leader, and leaving the party if neccessary
2. Keep supporting
We are not seeing 1. The conclusion is that, indeed, supporters of said party are either racists themselves, or worse, people that are fine seeing racist, homophobic, and sexist policy hurting the majority of americans.
Republicans did have a choice here. They didn't have to support that. Yet they did.
