For some reason, folks want to believe that I am highly religious since I do charity work and not simply because it is in my heart to do so.
I've done voluntary work most of my adult life, mainly because I believe in the furtherment of humanity (and protection of a healthy environment) through human endeavour.
As for treating people the way I want to be treated...I try to be helpful but treat people according to their behaviour. e.g. recently I was sick as a dog at work and had a collegue just watch me slog over the last part of my shift. I no longer give him a lift home. I lent someone a fiver, I didn't get it back, I won't help them out again. Because I wouldn't behave like them and they need to face the consequences of their actions. Anyone like me wouldn't get a negative response.
I was a nice guy when I was religious. I'm just as nice now. Nothing changed, morally or ethically speaking. There are good people in and out of religion, but for good people to do bad things, that takes religion -- as I think Sam Harris said.
Many religious people have bought the bill of goods that the source of morality is god, as mediated by their church, and therefore, that makes them better people. Everyone wants to be their best, so this serves as an inducement to keep them in the faith.
Of course, it's made-up nonsense.
I believe in treating people the way they want to be treated (the Platinum Rule). I agree that there is an assumption among some religious people that nonbelievers aren't as charitable or compassionate.
"Atheists and agnostics are more driven by compassion to help others than are highly religious people, a new study finds."
"Religious doctrines typically urge the faithful to treat others with compassion and to put the greater good before selfish interests. But when it comes to generosity, nonreligious kids seem to be more giving, according to a new study of 1170 children from around the world."
