I'd think that people were exaggerating if the evidence wasn't so clear.
They have police departments on Twitter posting that you'll go to jail if you say mean things about Muslims. It's hard not to laugh except that people are actually going to jail (where they're then murdered by Muslim inmates). It's like Britain has turned into a not-funny version of The Onion. A very frightening The Onion.
Then there’s the censorship too. Things posted on FB that friends/family in the UK never see. They’re literally trying to control thought.
They will lose.
