Is this a problem?
If public schools are funded with taxes, which they are, and ignoring the illegitimate nature of taxation, then don't the people funding the schools have a say in what is taught? Public or not, since it's funded with taxation then the majority gets to decide what is taught.
Of course, this is no surprise considering the problems of public property and public service.
Yes it's a problem. We have a separation of church and state. No state sanctioned religion.
You don't see that implying there would be no United States if it wasn't for god as a problem.
A lot of people home school their kids, alot of people take their kids to religious schools but schools that are funded by taxpayer dollars are not allowed to sanction religion. Simple as that. It's just another test, a waste of time and money to have to fight it. But it has to be fought.
