That's my evidence.

And of course you know it's not evidence at all, Joe. There are people like your grandmother in every belief - which would make it evidence for every belief- and they can't all be "true" in any useful sense of that elastic word. I'd posit Brother Gregory as counter- evidence to your grandmother. There are Brother Gregories in every belief as well.

As for belief or not, I couldn't give a frankly my dear. It's what you take from that belief that matters. And I can't see how the profession of a religion or the opposite has made the slightest difference to people's social values. As I've said before, show me your St. Francis and I'll show you my Torquemada.
