That is simply not true. One example is a hilarious skit by an Australian comedian (John Safran) going to salt lake city and knocking on doors asking if he could talk to people about atheism. The amount of violent threads he received is quite revealing. In my personal experience having lived in the US and several other countries, I found officially people can say much more things (i.e. due to the strong freedom of expression laws), but in personal settings you are much more likely to be shut down, fired, threatened with violence, ostracized... for stating unpopular (in that social environment) opinions, in the US compared to the other countries.
