> The idea that people's political beliefs, what, don't affect other people who live in that country? Is insane.
Yes, that is insane, but I don't think the person you're replying to or the FNAF guy believe that. It sounds like Mr. FNAF might actually be opposed to Trump to some extent on LGBT issues. However, he feels more strongly about other things (USA-China relations, abortion), and he, like all of us, only gets two choices. So he chose the mix of good and bad stuff that he thought was better than the other mix of good and bad stuff. I disagree with him so I voted the other way, but I'm not going to hold him accountable for everything Trump says or does, and I hope I am not held accountable for everything Biden says or does.
Presidents cause unnecessary death and suffering without exception. That's not to say that "everything's a gray area so nothing matters", rather it means that you can't just take one issue and be like "I can't imagine how you would vote for somebody who believes this". Maybe the other option was somebody who is ~3% more likely to start a bad war, for example. Or 3% more likely to lose an inevitable war. I might take a bible-thumping evangelical with a slightly higher chance of winning WWII over somebody with exactly my ethics in office with less strategic acumen. It depends on the actual degree of difference. I'd have to assign weights to things and sum them up, because it's democracy and that's what you do.
