I think it's a great idea even if the school doesn't charge anything. Schools are built for the communities, and the community should be able to use it, be that community a church group, Boy Scouts, the quilting club or whatever the community has going for it.Actually recently read an article where some churches are renting school auditoriums. I think it's a great idea because it generates income for the school....
I think you can say oh no. It's unreasonable to expect a school or any other entity to accommodate everyone for every reason all the time (back to the pleasing all of the people all of the time deal). "Well, if they can have a Chess Club, then I should be allowed to have a Backgammon Club, and you should have to provide me with a room for meetings, because if they get to have something then I should get to have it, toooooooo waaa, waaa, waaa and if I don't get to have it then they shouldn't be allowed to have it eeeeeeeether waaa, waaa, waaa."...my only caveat is if you have a school group of Christian youth if someone wants a Pagan youth or Jewish group you can't say oh no!
The people who think that way are the same ones who play musical chairs with the same number of kids as chairs.
