"Arrogance and fanatical belief had become a racial trait. The galaxy belonged to them, having been fashioned for them by their God, so everything belonged to them, and they could do with it what they wanted, and what they wanted usually involved subjugation, destruction, and death. Religion, a vicious and hearty meme at best, usually collapsed as civilizations became spacefaring, for most such belief systems, initiated when the world was still flat and thunder was the bellowing of gods, usually could not survive the realities of the universe and the steady abrasion of science."
