Yes. The bible has stories of justified gang rape, wars against and mass killings of unbelievers, and so on. Parents would be justified in saying, "I don't want my child exposed to that." Besides, what if other kids in the class come from families who come from other religious backgrounds?
It probably depends if you are religiously expansionistic or not.
Some people want to make sure that other religious backgrounds are ultimately stamped out, for example, those with a general theocratic political program.
I was just talking to one of our legal assistants. She was catholic going to a evangelical school. They were constantly trying to convert her.
