I've never gotten into a PC fight. I'm 100% sure that I would have if I had responded to a poster who grates every single nerve in my body. When I see their posts I just let them roll off my back. I don't see how being consistently negative is helpful to anyone, so I have to be intentional when it comes to ignoring this poster. I would probably be banned from PC by now if I had ever responded to this person. What gets me is that people seem to encourage this person's behavior, which I don't get at all.
