Nor was I aware that Mein Kampf was banned in NL and Austria. I'm pretty sure it has been banned in Germany since the end of the war, no? Having actually read the thing I can sympathise with the legislators, it has no redeeming qualities. Nevertheless banning books is a step in the wrong direction.
Hate speech I'll have to get back to you about. I'm really not fully apprised of where such laws apply and how they apply differently in different member states. I approve of hate crime legislation generally if it used as an aggravating factor to existing offences. I can't imagine how a hate crime could be that and not another indictable offence too. You beat someone up, it's assault, GBH, attempted murder or whatever. If you do it because the victim was selected as a member of a particular group, that makes it a hate crime and increases the sentence by, say 30%.
I can't see how hate speech can be indictable unless it also incited violence. I disagree with all blasphemy laws too.
