I don't know if you have ever noticed, but children are able to accomodate vastly different contexts, environments, value systems, etc and switch effortlessly from one to the other, without analysing the contradictions.

For example : bilingual children (including those whose parents don't speak the local language but learn it at school); those whose home environments put no value on learning or reading, but acquire these habits at school; battered children who learn to feel safe and empowered at school; children of divorced parents who have very different lifestyles; and so on.

Some people imagine that children will be confused by such differences. With respect to bilingualism, for example, people with no experience of the question are often convinced that it must slow children's development. In fact, it helps if one is consistent, using one language or the other with certain people or in certain situations, rather than mixing arbitrarily. But "religious" with the family, "secular" in school is exceedingly clear, and not a source of confusion for the child.

I have always considered this capacity to manage differences a very positive thing : enriching for the child when the different environments carry positive things; and giving the child an alternative when one of the environments carries bad stuff. It empowers the child to recognise that there are alternatives in life, and helps them choose between them when the time is right, or to determine their own path.

If, on the other hand, you find it important that your children should understand that there is only one valid value system or path in life, then it is important to limit exposure to the alternatives, and/or to forbid the child from experiencing them.

So, yeah, for my part, I propose to propose an alternative, in the school environment,  to a consistent and complex style of raising children with a ban on headscarves in schools.
