Part of the point of discussion on a discussion forum is hopefully to be able to convince others or to be convinced by their arguments?

Agreed but discussion with you is impossible. I must admit until today I'd always favoured the "theory" that the reason for your methods of argument was you are motivated by some personal grudge and that perhaps eventually you could at least accept some things said to you.

Having read another thread on a different today, I'm pretty well convinced that is not the case and that you genuinely do have a problem. I think if you had the idea that Joe Offer was a purple martian with 3 eyes, nothing said could change your mind. I'm even doubtful that a face to face meeting where could see for youself would alter your view. You would most likely then belive that martains are capable of disguise.
