Seriously, this is why foreigners shouldn't write about another countries legal system they know nothing about. (although I am now going to do exactly the same, so yeah...)
Just because America took the principle of freedom of opinion and bastardized it into something horribly idiotic doesn't mean that other countries should follow suit. In Europe (and pretty much everywhere else) we have freedom of opinion, everyone can state his opinion no matter how ontroverse, but something like "I fucked your dead child" is not an opinion. It's harassment.
Why should you legally protect someone who defames the dead and harasses his family?
Do note that another form of harassment is of course sexual harassment and this isn't protected under freedom of speech even in the US, now is it?
If you partake in racist slander in public this will also get you into trouble, right?
If you run around in a cramped train shouting "I have a bomb", there will also be consequences, right?
If you call the police to your house for fun you will also have to pay a fine, right?
If you knowingly spread false information in official media, you might get into legal trouble, right?
Freedom of speech was never an absolute right to do whatever the fuck you want, not even in the US. I know you like to see it as such, but that was and never will be the case. There will always be restrictions. Harassment is treated different in other countries, some treat sexual harassment as illegal, some add racial and religious harassment and some even add harassment on a personal basis in certain events.
There is no country with complete freedom of speech and that's perfectly fine, if you ask me.
