Secular humanist...what is in it for me?

On another list an atheist asked

“Secular humanist…what is in it for me?”

Is this a ‘religion of humanity’ and what is the payoff for the hard-core atheist to adopt it?

Secular humanism is a philosophy much like utilitarianism; that which creates the most good for people is the considered right. Or more accurately, it’s sort of an elaboration upon The Golden Rule.

Yes, and that’s what is in it for you…humanity.

…not a secular, by the way
