The one and only example I saw in this thread was a clear threat of violence, not merely an anti-Muslim statement.
People will go to prison as a result of posting things on facebook in their reactionary hatred, and I would defend their right to say so, as much as I would defend those who say homosexuals are going to hell, British soldiers are baby killers and even the Muslims who go around calling people degenerates and slags.
The UK's free speech laws are a joke, abused so easily for political censorship.
(1)A person is guilty of an offence if, with intent to cause a person harassment, alarm or distress, he—
(a)uses threatening, abusive or insulting words or behaviour, or disorderly behaviour, or
(b)displays any writing, sign or other visible representation which is threatening, abusive or insulting,thereby causing that or another person harassment, alarm or distress.
[Literally, anything deemed insulting, abusive or harassment].
(4)A constable may arrest without warrant anyone he reasonably suspects is committing an offence under this section.
(5)A person guilty of an offence under this section is liable on summary conviction to imprisonment for a term not exceeding 6 months or a fine not exceeding level 5 on the standard scale or both.”.
And then you've just sent a bunch of people to prison where they will eventually meet extremists with whom they share common ideals.
How on earth could that go wrong.
