what are we supposed to say again when christians ask us where we get our morality?

[naimless]

I don't want to murder, therefore I don't murder. I don't want to steal, therefore I don't steal. If you have these urges and only hold them back because of the threat of eternal punishment, you should really speak to someone about it.

Well I am happy you have lived a sheltered life thus far.

But let's say someone does murder someone or something close to you, or does significantly steal from you and the law cannot help you.

Would you seek revenge or forgiveness?

Perhaps as a 7/7 atheist I seek revenge, yet as a devout Christian/Muslim/Hindu etc. I seek forgiveness.

I can't see the motivation as an atheist to take a moral high ground, assuming there was no potential earthly punishment beyond my control and nothing existed after earth.
