Telling someone that they aren't allowed to comment on your history because they're not from your country and then commenting on another country's history is a funny one.
I never said that you weren't allowed to? Try learning to read.
Please show how Britain that has occurred in your example finger-pointing at Britain for ten years and how that shows it would occur in your country.
Ok censorship in the UK:
UK's Libel laws. How the actual fuck can you guys think it's ok to have the right to sue someone for saying negative things about you or "damaging your reputation"?
Your "terrorism" censorship laws are pretty fucked as well. How does someone writing poems on the internet (even though you don't agree with what they say) grounds for arresting them and putting them in prison?
These are just some of the many examples I can think of off the top of my head. Censorship has led to many of your rights being taken from you and your government gaining more power over you. Whether you care about it or not is irrelevant.
So yeah, seeing as how all this censorship has worked out for you guys I'm not in a rush to try it out in the US.
