The best first step would be to remove holy rollers from schools.
I taught Earth and space science as an elective in a public high school. This was a district north of Boston that had a sizable number of evangelical Christians. This included young Earth creationists. This may surprise you, but evangelic Christian students have a right to a good education that respects their cultural heritage the same as any other student.
At the beginning of the section on the Universe, I gave a explanation that we were going to be talking about the science. Students had the right to their own beliefs, all I asked is that they could explain the scientific understanding of the Universe and evidence behind it. I had some good students who were young Earth creationists. They had no problem with the material.
The only problem I had was with an atheist student who kept on saying... "that is why scientists know there is no God". She ended up dropping the course when I questioned her. She was upset that I didn't back her up.
I don't know what you plan to do with "holy rollers" since we have a strange idea that everyone has a right to a good education regardless of their cultural heritage.
