I haven't looked at the particular case, but nazism is a particular thing - given Europe's history it's there for a very good reason in most EU countries.

I don't know about the 'fat idiot', but in most EU countries that's more than fine so I have a bit of a hard time believing that was the sole reason - public figures are fair target for stuff like that. The limit is actually planning or inciting violence against someone or a group - again, the same as in the US.
