Why doesn't Britain have free speech?

[AL]

I read on a new-site that a boy may be prosecuted because he burned a memorial poppy on Facebook. I don't agree with it, but how is it a crime? I know you have a malicious communications act but that should apply to things like stalking and death threats, not opinions. Things like this interest me because I can see where this is all going. Government control over the internet. My country, yours and everyone else's. I looked for a petition to sign, but there is nothing. Since I follow these things I've noticed the majority of Twitter/Facebook "trolling" cases are from the UK. Why do you do nothing about it? It really angers me. You may not agree with what these people are saying but why let your government try to control it? They'll be banning certain sites next. They've already tried with your p0rn. It's the principle rather than the great, great p0rn. Are you nanny-state lovers or are you going to do something?
