The Toronto City Council has banned an exhibit comparing the anti-Jewish rhetoric of Adolf Hitler with the anti-Jewish (and anti-Israel) rhetoric of Mahmoud Ahmadinejad. I don't exactly know what was in the exhibition. But this prohibition seems to me to be prima facie both disgusting and dangerous. "Disgusting" because it puts up Toronto itself as a barrier to discussion of one of the crucial issues of our time, which is the tie between fascism and Islamofascism. "Dangerous" because it shows how fragile is the right to free expression even in free societies such as Toronto.
