UK has definitely gone waaaay overboard in their enforcement of speech. that said, UK and Russia, and China for that matter, are the same in that they prosecute speech that the government disapproves of.

I'll also be willing to wager that Russia's population is much more used to living under an authoritarian regime, so the average person knows how to keep their head down. people living in the UK still remember what freedom felt like, and are having a difficult time accepting its gone.
