Wow. Let's denounce a Fascist by...behaving like Fascists and arresting him for what he THINKS...
And you guys on the other side of the Pond like to lecture us Americans about Free Speech.....hmmmm
The only countries that have anti-Holocaust-denial laws are those that were under Nazi control during WWII, and therefore were directly affected by the catastrophe. So I think they have a pretty good excuse for arresting somebody trying to deliberately distort past events based on fabricated evidence, and also trying to claim legitimacy.
Suppressing the spread of antisemitic rhetoric in places such as Austria, given its past, is probably a good thing, wouldn't you say?
