I don't argue with them. I don't speak to them. I don't listen to them. I don't acknowledge their existence. Simply stated, I cut every single one of them out of my life. A few were dear friends for a very long time (20+ years.)
Any time I find myself in the same place/room/situation with them, I simply turn my back and refuse to acknowledge them. I really don't give a damn' if they know why I refuse to acknowledge them or not. If they're truly that damn' stupid I really don't want them in my life.
I tend to agree. We have irreconcilable differences which has limited resolutions.....a split...or war.
