Meanwhile/Umptious is absolutely the most difficult sort of editor/conversant IMO. He relies heavily on logical fallacies while completely failing to recognize he is doing so-- and simultaneously implying or even overtly claiming that others are doing so.

I'm not saying this to be mean to meanwhile... if he is completely sincere in his efforts, then I suspect he may truly be unaware of his recent disingenuity and that's unfortunate. The reason I am butting in with this is to get people to realize that their expectations of productive dialog with him at this point may be in all probability unreasonable. He either will not or cannot see his fatal errors in logic. Trying to convince him of his being at odds with reason is an exercise in futility at best. He is dug in and determined to defend his position.

Regrettably, pointing his actions out to editors and/or admins may be the only recourse it appears. Regardless, no one should be able to use Wikipedia as a platform for hatemongering, ad hominem attacks, misrepresentation of facts or spread of FUD. Period. That's not what it's for.

EDIT: I realized I was being ironically condescending and removed/changed some verbiage. I apologize to anyone offended, especially meanwhile. I don't really hold any ill will toward the guy, and really wish he'd step back a bit and realize he's going a bit overboard. He certainly seems intelligent and passionate enough... just a bit misguided.
