I'm not sure if I have said anything that offends anyone... looking back, I think I've made it clear that I don't believe in any of the current religions, and that I oppose religion being used as the basis for law. But I don't disapprove of anyone's right to follow whatever religion they want, as long as they don't impinge upon other people's freedoms.

Religion could be right - and I could be wrong. I don't think so, but it could be.

By contrast, it is some religious members who have made it clear that they disapprove of some folk's lifestyle. I imagine that public disapproval would be more offensive than believing something different, or opting for a different personal lifestyle. So I would not be surprised if Bingowing, for example, was offended.
