" I think it's perfectly possible to have a cohesive society and strong moral values without any religion being involved. It's probably a lot easier when you consider all the problems religious differences have caused. To us non-believers, it's just fairy tales anyway."
"Fairy tales" is a disparaging word for the big belief systems that give meaning to our lives. True, the great Christian myth needs tweaking to bring it up to speed. For on thing, it needs to have the supernatural bit left out of it, and I think that's the bit Hetty and many others object to.
Religion is a part of all cultures without exception, and I include religion look alikes such as Humanism, Islamism, communism, and fascism.
To avoid the bad religion substitutes and the authority freaks we need a reasonable religion that preserves a good moral code and tells a story of humanity that makes sense in everyday life.
