Evolution, Theory and Practice

Religious conservatives don't like the theory of evolution, and if they can't get it kicked out of school they at least want some alternate theories taught with it. Then they have lots of kids and prep them to succeed in the hyper-competitive worlds of sports or business, where the unfit are wiped out quickly.

Secular liberals are devoted to the theory of evolution and fight bitterly to keep it in the forefront of education. Then they have few or no kids and lobby the government to ensure a safety net for everyone so it's a cooperative world with no winners or losers.

Can anybody explain to me what the heck is going on here?
