France forbids vegetarian and vegan food in the schools

[Anoleis]

A violation of rights: "You must eat what we give you. No exceptions."

What they're doing: "We will not provide a meal that fulfills vegan or vegetarian dietary habits."

If some one is so involved in their morally superior fantasy, they can bring their own food.

What, exactly is the problem with this again?

Depends. If they prohibit religious stuffs to be used in public affairs, then nothing. If they arrest people for saying "god bless you"(or the french equivalent) when someone sneezes, then I think they're being a little pedantic.
