Ignore them. Many in the P&R are so blind in their beliefs that they don't care to hear what others have to say but rather hear themselves speak.
I recently added New2u to my ignore list because all he does is antagonize and make assumptions about people but refuses to acknowledge that "whoops, I crossed a line from arguing your point to insulting you" and apologize. So I figured for my own peace, I had to put him on ignore because it wasn't worth seeing what he writes and letting it get to me.
