Your articles on the post-election Iran protests mark the first time I've ever disagreed markedly with you, since I've been reading your articles. I frankly can't even guess how you're buying all this.

"Next, Obama did a truly courageous thing by calling out the holocaust deniers in a very powerful way."

I guess you and I might have different ideas of what "truly courageous" means. To call out a minority group such as Holocaust deniers and Holocaust skeptics, when one is in the power position, does not seem all that dazzling to me.
By contrast, men of intelligence and solid academic reputation are prisoners in Europe for the crime of producing respectable scholarship which challenges the numbers involved in the Holocaust and also the existence of gas chambers designed to kill human beings. Yes, prison.
Whether they are right or wrong, that would be a far better example of courage, in my view.
