France bans veils. Walking around nekkid is still allowed, however. (Nod to the Blonde, though she doesn't really advocate the walking around nekkid part; I added that.)
Here is the US First Amendment, including the five freedoms from majority tyranny:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances. (Written September 25, 1789)
Here is the French version of the same freedoms of religion (from the Declaration of the Rights of Man):
10. No one shall be disquieted on account of his opinions, including his religious views, provided their manifestation does not disturb the public order established by law.
11. The free communication of ideas and opinions is one of the most precious of the rights of man. Every citizen may, accordingly, speak, write, and print with freedom, but shall be responsible for such abuses of this freedom as shall be defined by law. (These two written August 26, 1789).
The American version was Sept 25, 1789; the French was August 26, 1789. Yet banning the wearing of headscarves in the U.S. is literally inconceivable.
The difference is that the U.S. version says "Congress shall make no law..." That's a protection against the government.
The French version basically says you aren't supposed to break the law, but there is no restriction on the law itself. The law can say whatever some bunch of meddlers want it to say. That's an establishment of state power over religion. Quite a difference.
Vive le difference!
