Funny how a religion that goes around absorbing the tribal wisdom of those it encounters is treated with more contempt than one that was written by a single dude who thought he had perfection dripping from his pen and converted people with the sword.
Evolve or die, and they evolved, and... they're stupid for it?
It's not that it's more rational, more intelligent or more logical to render the sex act infertile, you know. On one side, you have people saying "Choose to be decent!" and on the other side, you have people saying "I don't want to be decent, I want to be decadent and if Rome burns, not only do I not care, I don't want to be informed."
Logically, it doesn't matter if Rome burns. Caring is a choice. Not caring is also a choice. Not a superior choice, just a different one.
Once you reduce things to this level, logically, it doesn't matter if you kill, it doesn't matter if you burn the planet to a cinder, nothing matters.
Nothing, inherently, matters. But, you choose to have values anyway. And, there's no point in attempting to defend your values logically, or being upset when other people attack them with logic, because logic didn't have ANYTHING to do with EITHER position.
Feel free to kill for your values. Don't get yourself killed in return by accident in the implementation, but logically, dead people are no better or worse than living people, and as long as there are 20 of us left, we can always make more.
