What IS good, and how do we determine it?

[abaris]

Isis thinks it's ok and even good to kill infidels. But they are wrong. It is never moral to murder someone, and that is what it is regardless of what anyone may think. That's what I mean when I say it is a universal truth.

Really? So go tell that to your evangelical brethren in christ, who repeatedly call for killing gays and transgender people.

There's only a very thin layer of society preventing these people to act out on the very same vile impulses as ISIS. The only difference being the god franchise. And sometimes that layer breaks. Then some abortion doctor is killed or 87 people on the island of utoya. And please, don't come with the "no true scotsman" argument of Anders Bervik Brejvik not being a christian. He claimed to do what he did in the name of christianity against islam.

So christianity certainly isn't a safety belt against human depravity. And I'm not even speaking about catholic priests raping children - yet.
