Your examples are so many degrees removed that I do not think they are apposite. For example, people who supported Trump did so with full knowledge of his attitude towards immigrants, asylum seekers, etc., his rhetoric about building the wall (which many of his supporters cited specifically as their reason for supporting him), his "birtherism" re Obama, etc. Thus, they can much more strongly be said to affirmatively support those things than, for example, an American taxpayer whose money goes to help the Israeli government bulldoze Palestinian homes, or do any of a number of other foreign policy things that qualify as "evil shit".
So indirection washes away the evil? Is complacent support that much better than affirmative support?
Compare actively supporting "birtherism" to passively supporting blowing up brown kids with drones.
I think you're better off looking for common ground with the people around you, rather than putting up barriers based on which politician panders better to them.
Edit: Case in point: we disagree here. I don't hate you for it, I'd hope you don't hate me, and I think this is a fine conversation to have. The alternative is we could each say fuck you and go our separate ways, and the world is a slightly worse place for it.
Do you pay taxes to your government? There's a good chance you're funding some evil shit (among good things as well obviously).
Are you part of a church? Some of the people involved with that church probably do or have historically done some pretty evil shit.
I think life is messier than the picture that you're painting.
