Self interest

I'm not saying that truth is determined by who says it, nor have I ever. 
What I'm saying is that *when a lot of evidence is invisible* (as was the 
case with yours despite your protestations), people *will* use the 
characters of the arguers in determining the probable truth or falsity of 
their statements.

Fallacy or not, *this is the way people think*, and if you want to have 
anyone believe anything you say in future, remembering this might be wise.

Right now I wouldn't believe you if you said the sky was blue, unless 
confirmed by independently available evidence. Your every action 
screams 'bias' (because all we have available is your words, and your 
words are every bit as rife with ad hominem attacks as they were when this 
mess started).
