Well the interpretation of what constitutes as hate speech is different between the US and the UK, for instance. In the US, hate speech can only be banned in the case that it is intended to incite violence (or is likely to do so), whereas in the UK hate speech on social media can be met with a heavy fine/criminal penalty.

Now I don't "support" hate speech in and of itself, but at the same time I do believe that it should be protected under the first amendment (unless in the case that it is intended to incite violence). So I do think there is a bit of a difference, and altogether I feel that the United States stresses the importance of true free speech more so than its European/Canadian/Australian counterparts
