Would you like if all people became atheists?

So how can you judge religions on the morality of a religion's followers if there is no consensus between us what the moral or immoral actions are.

One could argue there is an underlying objective basis for morality that we all already at least implicitly honor, which is simply how much/little suffering and/or pleasure an action causes in other sentient beings.

The law is just a very, very blunt and imprecise instrument when trying to quanitfy this to come up with rules that ensure the least amount of suffering caused by any individuals actions.
