I have every respect for your devotion to your God. You should certainly be allowed to pray. You should even have the opportunity to have your children taught whatever religious instruction you desire, right in school. You should not be subjected to ideas (abortion, homosexual normalization, evolution, etc.) that you don't want.
That's what makes public schools immoral on their very face. They are funded by force, and they subject parents to unwanted ideas.
Eliminate public schools altogether, give parents back the money that is siezed from them by force to pay for it, and let the parents purchase the education they want for their children on the free market.
Socialism is the root of MOST of the problems in this country.
