No. But I have stopped following a couple of blowhards cluttering up my feed, and I hope they will do the same to me. We stay friends, if we want to check in on each other we do, life goes on. In my estimation, the best way to handle it is "This is my wall. If you disagree with me, feel free to say so on your wall. I'm not going to do the hammer and tongs routine with someone I get along with perfectly well otherwise."
