I understand, and have a similar situation.
There's a guy whom I would have called a friend in the past. His daughter and my daughter have been friends and were in school together since they were in first grade (now both college freshman), and he and I used to hang out occasionally before the pandemic (and the 2020 election). He was always an enthusiastic Republican, one of those who, if he had the power, would raise Ronald Regan from the dead and follow him as President forever. And he seemed to be more of a Romney Republican, on the conservative side but initially disliked Trump and the direction he was moving the party.
But something clearly broke his brain since the 2020 election. His Facebook posts are almost always political, and repeatedly uses the term "woke" and several other MAGA tropes, almost to the point where it looks like a Russian bot has taken over his account. I haven't hidden his posts, because I'm somewhat fascinated to see the turn he has taken. But it's also so shitty that I just can't consider him a "friend" anymore, and I have no desire to reconnect with him anymore.
