I'm curious to see some references and figures here. As far as I know, only Hate Speech, and holocaust-denial are forbidden. Libel laws apply too, and some people are trigger-happy with them though.
But accusations of Hate Speech are being broadly abused. For example, a guy I disagree with on almost every issues (economy and immigration) Eric Zemmour was accused and found guilty of hate speech for saying that most people in jail are Arabs in France. This is a fact that was confirmed by many judges and yet the guy was still sentenced cause he hurt some people's sensitivity (I guess...). I'm half Arab myself and still it's obvious to me that most people in jail in France are Arabs (mostly cause they're the poorer), but still, it's true.
