I wuldn't bother, leave them to it. Either that or take the moral high ground and actually answer any direct questions with direct answers. Either that, or what Pete said.
TBH, if he were that interested in communicating his message, he'd actually clarify it in the first place, and would respond to reasonable questions with direct answers, not more mumbo-jumbo. :Y
I'm sure he is. I'm intrigued as to which thread he thinks he's asking questions in. It seems to me he does nothing but deliver statements of paranoid fiction. I can't think of a single open topic he's broached other than this one.
Wait a minute guys. It's just dawned on me. He's talking about US! In THIS FORUM! Not some other forum that he's asking us for advice about at all! I am more shocked than that time Maximilian thought we were a serious grown up serious tech forum about serious tech. I miss Maxemilian even if I can't remember how to spell it. I think the first is right but I have this idea he's got a different version, could be totally mistaken.
So I guess the answer is that the teetotal (haha, pedant opportunity! he said "tea total". teehee!) vegan etc and so on person would approach them by rambling on vaguely and always be evasive if pressed for details or clarification, by posting more inconsequential rambling. Because that's what happens. But there would be ways to have it all better.
I was rather pleased about the reference to 'fucking ignorant Yorkshire mentality' as I feel that it was intended to embrace me (among other notable fucking ignorant Yorkshire mentals).
I am certainly going to make sure that I make frequent references to the inconsequentiality of Hamsters in my future posts.
