You threat with weapons. You regulate like that only if you wanna raise a bunch of idiots afraid of words.

You can use your words, freedom of speech does not work like this. There's a difference being a critique and threatining someone..
It is absurd when you make rules that "protect freedom of speech" that punish people's freedom of speech against other people's freedom of speech. Plus, until 27 years old children don't reason their language, they just talk their emotions. It is not a fair thing to do in general and mostly because it is also political and it is about US again indirectly provoking the other big guys. It is just a lame politics. Weather we should talk hateful or loving to each other, that is another topic and I don't think we stand pretty well at this topic everywhere with all this shit happening in the world. Jailing is an abuse against people that empowers fear.
