If your kid can't go to a school beecause of their lack of religion, do you think your taxes should still have to pay towards it?
Do taxes currently fund religious schools?
Here they do, but, religious schools does not mean that much.
All schools have to meet the same standards, and get the same funding. So, a Catholic school will teach the same stuff as other schools, in their ethics and how they think about humanity, they are influenced by Catholicism.
I live in a small village, there are three schools. Public, Catholic, and Christian. On all schools you will find people from all kinds of backgrounds. Religious or not.
My kids go to the christian school. The public school was doing really bad when I had to choose, people take their kids away from that school still. So, I visited the one closest to home beside the public one. It looked good. I had an interview with them on how evangelical they were. They are not. Kids do get a story based on a bible story twice a week. And the day does start with a prayer. No winning of souls though, and no connection to churches.
And my kids have had no problems with their critical attitude on some things either.
