Hamilton, yes the freedom of speech is included in "The Declaration of the rights of man and of the citizen." that appears in the preamble of the Constitution, but it is not as strong as in the US Constitution where is quoted in the 1st Amendment. There are others laws especially for that.

Therefore, France is using Rap music as a scape goat and practicing censorship and stopping freedom of speech.
That is false. It's not France (the Gouvernment), the condamnation of the lyrics comes from a few politicians from the republican party. and this is not the first time, but there was no justice decision that condamned it, and I guess there won't be either this time.
So, I think you can not accuse a State from politicians critics!

You live in a country where the State bans Muslims from wearing their traditional clothing in schools or carry religious symbols.
That is true, but this law doesn't apply only to muslim, but to all religions: christians and jewish too (with their own visible signs).
Note that this apply only to public schools, private schools can do what they want on this subject.
The aim is to ensure people's religion as a private matter. (I wouldn't like to be muslim in a public school where 99% are christian and show it by official prayers, signs, etc)

Even their notions of freedom of religion and seperation of church and state are upside down. Don't the churches have to pay rent to the state for land?
Churches are treated like any private company, they rent, or can buy their land. But all churches (or mos) that were built before the law in 1905 (95% of churches) are totally financed by the State.
