Personally, I don't think I'd ever be friends with a Trump supporter, nevermind date them.
I'd happily date someone with different political views to mine, but I draw the line at supporting someone because of or in spite of fascism and bigotry.
I did for 3 years.
His true colors started coming out in the final months of the election and that's part of why I broke up with him.
His support for Trump isn't what made me break up with him, but some of the racist crap that he started spewing were part of the reasons.
No. Trump supporters consists of racist, homophobic fascists who promote white supremacy. I would probably end up walking into a lynching party for myself.
