Just to clarify, French schools don't have school uniforms. The only rule is that they can't wear 'visible religious symbols'. So it's not a matter of us nasty G@d botherers wanting special treatment, it's a matter of French girls who are having bad hair days or thinks scarves are fashionable being able to wear them unless there's a suspicion that she might be doing it to please Allah, in which case she has to expose her hair for all the good French men to see if she wants to go to school.
