Good answer & an interesting concept. Let's consider. The Young Earthers (of which I'm not) take over and start teaching in our public schools that there is a God, you are supposed to love your neighbor, and the earth is 6,500 years or so old. And that's a worst-case scenario, if I'm wrong and extremist on my side take over.
That's not the worst case scenario, since the age of the Earth is geology which is not taught in High School
The worst case scenario is they teach that evolution is not the underpinning of biology, so we never get good biologists anymore and we end up with incompetent doctors, no medical research that means anything and a bunch of dead people.
No. Based on past history we would end all progress in science and denigrate to a drug infested society with death the sentence to all "non-believers".
