National laws are largely based on the local morals; for instance in Europe breath is more or less indecent to show in public. A woman being topless on the beach, even in France, could be arrested, in theory (in practice it would just be "please put on some cloth, madam").

The laws are (usually) defined by the people of a country, based on their idea of morality, and are totally in their right to reject blasphemous stuff or whatever. It's their home, after all.

The only thing non-negotiable, to me, is that the Declaration of the Human Rights is universal and no law, anywhere, should go against them.
