I disagree. No religious school should get tax payer money unless they want to pay taxes.I think the argument is a religious discrimination one. Religious charter schools don't get access to state funds and other charter schools do. The only reason is religion. So do you not give them access because of their religion (discrimination) or give them access like all other charter schools but now the state is funding a religious entity. I can see it either way. I'd understand them allowing it, just as long as they also give the Islamic school down the street access to the same state funding.
That's my very simpleminded understanding.
