For example, saying "the Holocaust is a hoax" in Canada or Germany can get you in jail. [2] Saying something that even hints that women are different than men in the UK will probably result in you losing your job. [3] I'm pretty sure the same is true in the US, at least on the East Coast.
Exactly that. Surprising how many people misunderstand this; but then most of us live in a free country (so far).
