Not only that, but if your child isn't of the inclination to be religious, it will also be a painful experience. Questioning the why behind and benefits of the religious faith of the group leaders and other youth group participants is a great way to be bullied and not only that, told you're wrong for thinking logically. That, plus the associated moralizing (i.e, "there is only one way, the right way, to be") I think are pretty damaging for kids.
Societally we are accepting of many more ways than the one proscribed by many churches. Being of one sexuality or another, or one morality or another, as long as you respect and help your fellow human beings when they are in need, should not matter. I wouldn't expose my kid to anything saying otherwise if I could help it.
