or "Good civilizations shalt not commit acts of heinous genocide"

I was just wondering if the invasion system in Galciv2 will be like in Galciv1, where you shuffle your populace onto a transport and then send it to an enemy system. Once it gets there the two populations duke it out until only one remains, which essentially means you commit genocide every time you invade. Not a very good thing if you're aiming to be a good civilization.
