It's been fun - or maybe not. Anyway, I've been de facto banned from Tim Blair's site for pointing out that he and his fellow denialists ought to put their money where their mouths are, and bet me over global warming. The site administrator had resorted to inserting obscenities into the comments I posted, thereby proving that the denialists are right and the consensus science position is wrong. I consider that a ban, and this is the banning thread if you want the details.
They lasted longer than the "Free" Republic, but with the same result - shut someone up when they point out your hypocrisy.
