I think all Republican politicians are genuinely terrible by default simply by being affiliated with the party. Even the ones who try and toe the line between parties like Romney, Murkowski, etc. I just think if you have the kind of opinions/views that Republicans have, it's very hard for me to believe that you give a fuck about anyone at all. Republicans are constantly doing/supporting things that hurt the majority of citizens.
Do I know people who are Republicans who I'd consider to be good people? Sure. I'm sure there are also people who I know who I'm not aware of their political leanings who are Republicans but on the surface they're good people. That doesn't justify their shitty views though. Before Trump, I didn't really care that much who I knew who was a Republican. I didn't agree with their views, but it wasn't the end of the world. Post-Trump though, I think being a Republican means that you're okay with all the ridiculous and disgusting treatment of the American people that has only gotten worse and worse, and it caused me to look at anyone who is a Republican completely differently.
So are there "good people" who are Republicans? I guess, but they're still complicit by being affiliated with the party and supporting the party's trash policies and hatred. If I can help it, I go out of my way to avoid people that I know are Republicans now. Just not the type of people I want to be around.
