To an extent, I think that's a good thing. It keeps challenging points of view in my feed. If I ever found someone truly abusive, I'd block them. But that's never happened to me. As I said elsewhere, my discussions can get pretty heated, but I try always to be respectful.

At the end of the day, I'm more concerned with how my point of view appears to lurkers than to someone I'm debating. I'm unlikely to change that person's mind in any given convo.
