I know a few people like this. They see everything through a political lens. It's exhausting.
Sorry your dad has no chill. Mine was much the same way. Maybe call it to his attention in a funny way. "You know dad, sometimes a cigar is just a cigar."
The catch here is that I don’t like people who try to destroy my friends’ lives. Since the conservative platform is to destroy many of my friends’ lives, I don’t like people who follow the conservative platform. Conservatives like to treat this as bigotry when it actually isn’t. It’s intolerance of intolerance, which is not just acceptable, but necessary.
Yeah there usually not much you can do but hope for a change. Mine had drinking problems and was much like this. Went sober finally and he still is similar politically just not insufferable and can take a joke so it’s far more pleasant to be around him.
