Sure, for awhile. Like I said, it will take a few generations.
But, the moment you abolish Government Schooling and give Creationist Parents their money back, you've got something like 55% of Americans willing and able to pay for Creationist schooling.
That creates an enormous shift in educational demand, in favor of Creationism, on Day One. Continued Creationist numerical superiority in child-bearing will continue to reinforce those trends over time.
I'm unconcerned about the results. Given the vast numbers of Parents who want their children educated in Creationism, the market for Creationist education will grow, and the market for Evolutionist education will shrink.
Subsidize something (Evolutionism), and you will get more of it.
Eliminate the subsidy, and you will get less of it.
This really is Basic Economics.
Do you think that the Catholics are going to go anywhere or change their position?
Catholics are a large and expanding % of the American population.
Catholic schools are the #1 private school system in America. They teach evolution.
