When you step on a blade of grass, does the grass not suffer? What level of moral development are you on? Morality in these matters are all relative. As for the superiority of western civilization, yes I agree there is a temporary superiority. Not one that will last forever or even for that much longer.
NO, a blade of grass does not suffer, don't you know the difference between a conscious, sentient being like a cat, and an unconscious being like a blade of grass? And morality is very far from being relative. What are you saying, because in China torture is practiced therefore in China torture is relatively moral?
And the superiority of Western civilization does not lie primarily in technology or economics, these are secondary side effects. The primary superiority is in the idea that we are all precious in the sight of the Creator, and cruelty, even to an animal, is simply horrible and unacceptable.
Because the Chinese have no such idea, they will never be a great civilization, no matter how far their economy or military goes - all of which I might add, is simply by COPYING the Western world! The Chinese contribute NOTHING original, only copy and steal while screaming how great they are.
