One of the responses to the publication and dissemination of the Danish newspaper's cartoons (and a few fakes, one of a modified photograph of a French Pig-Squealing Championship contestant) the Iranian newspaper Hamshahri is holding a contest for cartoons about the Holocaust. You can probably imagine the results already. The idea to claim that the free speech argument for publication of the Danish cartoons is a double standard.
The sad thing is that at several European countries have laws on the books that ban holocaust denial or revisionism. Thus Iran actually has a point. One would think that after WWII there would be an embracing of free speech in its entirety. Alas, that is not the case. The cause of the problem was misidentified and the wrong treatment applied. It's not just Nazi or fascist speech, bad as it may be, that is a problem, but censorship itself that is a problem. "Bad speech" cannot really be eliminated, but only driven underground, by such means. To really knock it out and more importantly, the bad ideas behind it, it needs to be dragged out into the open and exposed for what it is rather than hidden.
Denying the holocaust is distasteful, but should not be illegal. Let a fool look like a fool and point out his foolishness. That's better than making him the holder of a "secret the government doesn't want you to know" or some such nonsense. Some will still never be convinced or will continue to spout nonsense as trolls, but they will look silly when they have to explain away the newsreel footage, amongst other evidence. Maybe they ought to be called newsreel deniers. After all, how many "they faked the moon landing" folks does anyone take seriously?
The best response to Hamshahri's contest is to publish the results, as distasteful and distorted as they will likely be. The Jyllands-Posten editor who published the original twelve cartoons understands this and thus his reply: "My newspaper is trying to establish a contact with the Iranian newspaper, and we would run the cartoons the same day as they publish them."
