lots of other thoughtful responses here but simply put, no. if someone supports a harmful political figure, they likely believe that figureās beliefs or they at least donāt care enough about each impact of that politicianās whole platform. we canāt only think about how things impact ourselves; being kind to others is the bare minimum.
and there is nuance, like if someone believes we canāt abolish the police but thinks the current system is bad, so they support a politician who increases social services (that prevent crime), thatās different from someone who supports a politician that justifies police violence. the latter is highly, highly ignorant; but the former acknowledges social issues, which indicates space for further dialogue and growth
from an organizing perspective, i do believe in educating and calling in etc but those are learned skills and also a totally different thing from friendship and dating. you probably canāt just āfixā the views of friends or partners, and should not just leave that as a caveat of your relationship nor put up with their beliefs because you think you might be able to educate them.
article linked is specifically about dating but itās a good, brief essay
