It's really sad, in my opinion.
I've maintained friendships with most of my friends who have differing political opinions, because we've been able to maintain a basic level of respect for each other despite disagreeing, but there was one friend I had to cut all ties with because somehow this election managed to turn him into a reactionary who supports racial segregation... yeah.
I didn't even necessarily cut ties with him because of his views, I'm a strong believer that the better road to take is always to try to have conversations with those I disagree with and try to persuade them to more reasonable avenues of thought (and I've actually been successful at this in the past), rather, it was more because he became a very aggressive, abrasive person who started lashing out at people and just generally being an asshole because he convinced himself that his ideology gave him sufficient grounds to do so. Things came to a head when we went to exercise and he spent the entire time trying to convince me that trans people are the devil and that I'm a "fag enabler" for having trans friends/having had a relationship with someone who was trans. Apparently he also has been doing absurd shit like telling his brother, who is half American Indian, that his race is the reason why he's bad at math and doesn't like classical music. The dude's gone off the deep end.
I'm pretty upset about it, because I've gone out of my way to make sure that I don't let political differences ruin my friendships, but he's changed so much over the past year and I honestly don't recognize him anymore. He used to be rational and sane, and we were best friends for almost ten years, but this whole alt right ideology has taken him over and he seems to be beyond saving (it all started with Alex Jones). You can't reason with him by way of showing academic studies that prove his various viewpoints wrong, because he's convinced himself that "the Jews" have "infected" academic thought and that, therefore, it's all fictitious. Almost any evidence one can bring up that's contrary to his awful opinions is defeated by this mysterious strawman that he can manifest into any form he wants. It's well past delusional and starting to go into crazy territory, and I'm really worried about his mental health. Part of me feels guilty for disassociating with him, because now it seems he's stuck in an echo chamber filled with that garbage and he's most likely going to become more and more unhinged. I'm genuinely concerned that he's going to end up hurting someone.
No trace of him seems to exist anymore, but I miss my friend, GAF.
