I feel there is very little we can do individually to change people's minds or turn them away from fascism, or even to get them to stop turning their own brains into soup, but you can still show them there are consequences to their actions.
Telling my own friends / relations what I think of them and cutting ties with them has done nothing to bring them back in line with normal human values, but at least I am not burdened with the guilt of my association, and maybe one day enough people will cut them off that the loneliness gets to them and they begin to re-evaluate their lives.
It is literally the least I can do. Any sadness I felt was heartbreak that they could be so shitty to begin with.
My mother was the only person that continued to call me by feminine pronouns, friends, family, coworkers, strangers or otherwise. I could forgive initially but it had been years of trying and pleading with no give.
After a while it was blatantly ridiculous, bigoted and beyond "mistakes" because at that point i was burly and bearded, lol. Had to cut ties for my own mental sake and honestly physical safety. it was sad but also a relief.
Yeah I have family like this. I pass completely as a neocons Mormon daughter (look I like cottage core), I remember one time at a family function I kept being referred to as the son of so and so and everyone was so confused and even seemed to be concerned that the guy saying it was going senile or having a stroke or something
