Daniel Dennett has an interesting proposal.  Teach religion in schools, in a fact based way.  Similar to how other topics like math and history are taught.

“No religion should be favored, and none ignored… This should all be part of the mandated curriculum for both public schools and for home-schooling.  

As long as parents don’t teach their children anything that is likely to close their minds — through fear or hatred or by disabling them from inquiry (by denying them an education, for instance, or keeping them entirely isolated from the world) then they may teach their children whatever religious doctrines they like.”

It’s a decent callenge to parents who wish to indoctrinate their children with a specific religious viewpoint.  If their religion is so good, let it be opened up to compition. Some religious groups and parents are already opposed to such classes.
