Where do atheists get their morality from?

[Whateverist]

My morality is based entirely on the Non Aggression principal. I do not initiate pain on someone else or take their property. I certainly don;t use some tax to justify me doing just that.

I do everything on the basis of voluntary exchange. I am also a vegan for that reason.

You must be irritatingly nice.

If I ever survive a plane crash in a mountain pass where to survive we are forced to eat each other, I hope to have some vegans on board.
