That would be my guess also. There is also the supposedly devastating argument, that he lost several months ago without realising it, that appears in every thread, at least every third post, impervious to relevance. I have a sort of semi-permeable ignore feature, in that I have to make an extra effort to read what he says. Most of the time it isn't worth it.Gee, that poster jumping into a conversation without regard for the context, and making a fool of himself? Nah, can't be. Not him.
I swear he runs around, looking for posts by one of the people he's obsessed with and then, without even looking at the conversation, just posts a negation of whatever they said.
