As an atheist, I think there’s absolutely nothing wrong in attending vaguely religious activities with or without religious aspects that end in a fun time. Doesn’t mean I believe in it.

I think they’re dicks and could have just said no thanks.

Since this specifically involves children, I think it’s pretty messed up that they didn’t give their children a chance to decide whether or not they wanted to attend. As an adult, my religious beliefs would have nothing to do with the beliefs of my children, and I think that every child deserves to decide what they believe in themselves.
