This idea that god is on our side because we are more righteous than anyone else is key to they way in which religion is used as an organizing tool by those in power. Forget that little commandment that tells us not to kill. That's just a technicality.
The logic is flawed from the get-go. You say your god is a loving god. You say your god loves all of "the children." You tell us that your god is pro-life. Yet you believe that this god of yours would, and should, cast his blessings on the people carrying guns around and firing on other folks because of the color of their skin, or the clothes they're wearing or the religion they practice or whatever reason we're at war somewhere in the world.
Enjoy your opiate.
