I know you're not making up the testimonials. If he's implying or directly saying that they're made up, then none of us have to feel bashed personally because he's accusing people that don't exist. I for one, don't care a lick even if he is accusing me personally of lying. It certainly doesn't appear to be personal, I see no evidence of any posts of "negative accusations" of the other members of this forum, but if it's there it's probably related to the topic of debate, not an accusation that any of us are liars. Of course there's no reason for anyone to resort to ad hominem attacks against you either, such as calling you a liar and whatnot, unless they feel as if they're losing their power when really they're just losing their self-control. It reads as nothing more than an act of desperation.
If anyone did look at his posts, he does spend a lot of time helping others freely, which is one reason why I said you both have more in common than meets the eye.
