Ex-muslims routinely complain that youtube censors their videos criticizing islam. Videos of brutality (that often contains legal proofs of crimes) are removed if they are used by some hate groups, even if the intent of the recorder was to denounce violence.
In France, hate speech laws are now extended to jail terrorism apologists. OK, why not, I don't have a lot more love for them than I have for nazis. But we are also at war with ISIS, that is labeled a terrorist group. So taking its defense potentially leads to jail and censorship (it has already, actually)
And this is a worrying situation for a democracy: we are at war but we can't have a debate on the justification of that war, because such a debate would require making arguments in favor of ISIS, which is illegal.
Remember, fascism is an ideology that comes from many sides. It is not because there is a racist buffoon in the white house that we must not watch the other fronts it could come from.
