However, you cannot hide behind 'free speech' as a means of causing undue suffering, or for the purpose of causing commercial or reputational damage to an individual.
Finally, artistic expression in the UK, at least on television and radio, is a lot more lenient than in the US. Oddly, this doesn't apply to video games where it's the other way around (UK games have age restrictions), and quite frankly I think censorship is a bigger problem in both countries than the principle of allowing harmful speech or not.
Britons are also protected by various Human Rights treaties, which Americans are not, as well as the European Convention,
for the purpose of having a dig at Britain. It seems you're still upset about Trafalgar.
