Every person gets it's moral values from the culture he lives in. It has very little to do with his instincts or "humanity"......
Much of the moral code has to instincts or "humanity", but... moral values based on culture can override those more basic rules.

But as the "golden rule" seems to a very effective way to build a society on, so I say that we stick with that. That I personally agrees with them, doesn't make it a weaker argument.
