Some people interpret freedom of speech as TOTAL freedom, and that is never the case.
The law of any country so far as I know will always have some topic that cannot even be approached, by virtue of their own history & circumstances.

Even Norway, Iceland, Sweden who generally have a decent reputation for these things have their own prohibitions. No absolute freedom exists.
Also people's opinion of free speech is usually based on the prohibition of the topic of THEIR interests.

A better question IMO is where do we rank on the relevant scores & indexes that study said rights,
but even then it's flawed because the 'measuring ruler' for them is based on values from their own countries which is not exactly a universal truth.
