I too find this decision a bit worrisome, but I can't think of any easy way to draw the line between private groups that ought to be let in vs. those that ought to be kept out of public schools.

It's interesting that the guy on MPR who represented the Good News Club said he wasn't against pagans, Muslims, etc. also using the public schools. I predict that elsewhere most fundamentalist groups will be outraged if Scientologists, Wiccans, Nation of Islam, etc. try to hold meetings in public schools. I just hope they don't use violence or intimidation to keep them out, since they obviously won't be able to use legal means any more to keep them out.

Unless, of course, we ban ALL private groups from public schools -- Boy Scouts, Girl Scouts, whatever -- which, now that I think about it, is probably not such a bad idea.
