Read Sam Harris, who is opposed to using religion to set “morality.”
He cites islam and the fact it preaches so much violence to spread their word.
And he cites Catholicism for their protection of child molestation by priests.
He believes science is capable of discerning the best overall morality.
The Law of the Jungle.
Sam Harris is an interesting case, because he really doesn’t think science is the end-all and be-all. He thinks we need drugs and Eastern mysticism to fill in the gaps where science doesn’t.

You know, pretty much anything but believing in a real God.
That's exactly what Hitler thought too.
