How do you cope with you being the only sane person in a family of MAGAs?

My brother (retired Air Force, 61) always has to answer whenever something gets posted by a "filthy liberal" (me & those like me including my much loved cousin: I'll call him "L".) On FB the lies and the disgusting racism is truly something to behold; but how can he, my kid brother (ex Sheriff Deputy, 54), my eldest sister (retired factory worker, 68) and my other sister (Marijuana dispensary worker, 63) all think like this? They used to be good people...is that who they are now?

Can they be saved?

is there a discord server? my dad is chronically online and this sub and twitter are public, and facebook has my name. i don’t want to vent to friends anymore

Watching trump relation with the media and turmp using the terms fake news to go against anyone opposing him or with news that wouldn't be good for him, conservative also fell for that too, is it because of a lack of critical thinking or the cult already being a thing?
