A follow-up, now that Ahmadinejad has demonstrated at Columbia, that, yes, he's still spouting Holocaust denial.
He pulled a number of things from the standard-issue Holocaust denier trick-bag that I thought might be worth holding up to the light a little bit. In particular, I wanted to look at the "why shouldn't there be more research" bit and the "why throw historians into jail" bit. (I know, as if Ahmadinejad has room to complain about throwing dissenting academics into jail, but there you go.)
Update: interestingly, if you read the comments you can see someone going, step by step, reproducing the various mendacities I mention in the article. And check out his more persistent upraters, if you'd like some excellent examples of what it means to be a useful idiot.
Second Update: say goodbye to one purveyor of standard-issue Holocaust denial patter and two useful idiots.
