So it seems free speach is only allowed these days when it conforms with the views of the establishment. Regardless of whether the views these people hold are moronic or not.
Didn't some guy get sent to prison last month for writing something on his facebook wall and then deleting it later when sober?
Free Speech and peaceful protest is one thing, but acting in a deliberately provocative manner that is intended to cause tension and make the general populace angry is something different IMO. It's not like they're on speaker's corner.
Instead of banning them, give them one way tickets to a country that operates in the manner they desire then ban them from re-entry to the UK.

I agree that the idea of social networking "police" is quite unnerving though. I'm sure many people have posted or said stuff they regret when drunk. I'd have thought you'd have got off under diminished responsibility or something.
