By moral I meant what most societies accept as moral, and mostly in relation to the past. Like, most people will now accept that being gay is fine, slavery is bad, killing people to convert their religion is bad, killing people cos you can see more than their eyes is bad, pedophilia is bad, etc. According to the books of the biggest religions I know, those things were perfectly fine, so I don't see how religion cares about the individual or society.
I don't think I need to define 'moral' in order to make a historical claim. I think humanity by and large progresses against religion, not because of religion. Religion is actually what's holding humanity back.
But, like I said, I'm an atheist, so of course I would believe these things! A proper discussion would start from 'does God exist?' and 'can we have objective morality without God?' and things like that. Mostly I just wanted to say that there are no examples of non-religious societies that have no guiding principles. It's impossible for any conscious beings to lack values. All societies have values. Secular societies are proven to be much better and happier than theocratic societies.
