In what way would you like to hold them responsible? If there are reprisals for voting, do we live in a liberal democracy?
Edit: If by "hold responsible" you mean "be mad at them" then yes, of course you can, I can't read a comment section that isn't mostly that, and you knew that before making this comment.
You make it sound simplistic. I mean calling them out, demanding an explanation. You have friends who support this then let them know you think they are wrong.
All these horrific regimes throughout history, how did it happen? The majority of people agreed with it or was a vocal minority left alone because most people just wanted to avoid conflict?
I call this selfish. It's like hoping the problem gets solved later that way you get to maintain your relationships.
If you want to blow up personal relationships over politics because you think it will help, be my guest. People do it routinely. If it is "good" is an open question.
Because you stated you "hate Republican voters". If you hate Republicans (as a method of "holding them responsible"), it doesn't really make sense to remain friends.
Why would you feel the need to state this? Obviously it would and it should. If Trump was a Democrat and the same situation was occurring then Democrat voters should be called out
