I’m at a conference and the moderator at a session that I attended gave us an anecdote during which she said “I’m a good Catholic girl”. Was I offended at her injecting religion into a secular meeting? Of course not. She wasn’t preaching to us, it was just a passing comment, inserted for humorous purposes and we all laughed.
But what if she had said, “I’m a good atheist girl”? I bet you that that there would have been sharp intakes of breaths and some mutterings that she had delivered a gratuitous slap at religion. This is the protective shield that religion has built around itself that has to be dismantled.
