This is a program run by the government right? Juvie? Or is it a private organization?

LOL, maybe you could anonymously let the local wicca, pagan, whatever groups know that they can come in too. If the Christians are there, they can't deny the others.

If this is a gov agency, then this could cause a lot of trouble, if someone sues over it. The government cannot force religion on people because of the separation of church and state. I wonder what the ACLU would have to say about it? Does the ACLU know that this place is doing this? All it would take is for a couple of kids to contact the ACLU about being punished for not participating in a required "religious" activity in a government run facility. Because that is the government pushing a religion on someone, and the Constitution absolutely forbids that. These kids might even be able to get a settlement out of it for having their right trampled like that. Then your ucky supervisor may find herself without a job.

There are many groups that can facilitate socialization and "brotherhood" without it being religiously oriented.
