We don't go to church, so no one is bugging us about it.
I think it would be highly inappropriate for one parent to make another parent feel pressure to defend her position about whether or not to send children to CCD.
I can't imagine how that conversation would go after the following exchange:
Person 1: Hey, are your kids doing CCD?
Person 2: No, they're not doing it.
Person 1: Oh, okay.
Where does Person 1 go after that without being extraordinarily rude? That's awful for someone to put you in that position.
bmerr:Same answer when they ask why we didn't baptize our son... because we're not religious.
