Hey Liz,
I had a similar experience. Just after I adopted my son, he announced that he wanted to be a Boy Scout. There was an Episcopal Church that offered scouting to all boys regardless of faith. But, the leader, filling out the application, asked, "Your religion?" My son proudly declared "We're Irish!"
The leader did not however see the humor in it. He was shocked that we were atheists. But that is another story.
