I mean characters who specifically fight crime in the name of their religion. There are several Jewish superheroes, true, but apart from Sabra in the MU, I can't think of any who have a Star of David emblazoned across their chest. (And as far as I'm concerned, she's disqualified because she's named after a prickly pear.) I would have said that people care very much when Christians complain. I would have said that one of the main reasons why we don't have more religions represented is because the editors are afraid that Christians - specifically the nutball right-wing evangelical type who believe multiculturalism is a sin - will complain.
