Where do atheists get their morality from?

[pocaracas]

So much text... so little attention to precious detail.
Theists claim their book has all the rules of morality.

Everyone else... well, in most of the world, have another book, let's call the "The Law". comprised of The Constitution, the Civil Code, the Penal Code and whatever else.

Inscribed there are all the rules of unacceptable behavior within our society and respective penalties.
This is not a static book, it keeps getting updated to suit the majority's views.... you've heard of democracy, right?

In the opposite corner, you get static religious books with strange rules and respective punishments... .well, maybe they weren't so strange back when they were written, but they are now.

The Law says: do not kill another human being... or you'll go to jail and, in some corners of the world, get killed.
This is where most people's morality comes from. The Law.
Theists like to pick and choose the parts of their holy texts that match The Law, while forgetting the others.

Unfortunately, there are countries where the holy text is The Law.... I'm glad I don't live in such place.
