There are already plenty of laws in France and most (perhaps all) other countries that restrict freedom of speech. Examples of censured expression include but are not limited to: Holocaust denial, hate speech, some forms of pornography, leaking state secrets, harassing communication, copyright infringement, libel and slander. I don't think that freedom of expression is absolutely permitted anywhere. There are so many exceptions to it - many of which are necessary for a cohesive society - that it's pretty much an invalid concept in real terms.
