You are mistaken on Constitutional grounds about at least two matters. the modifier "unless parents agree 100%" does not make it constitutional. Not even if all taxpayers in your school district agreed would it be constitutional. The government - state, federal, local (including school boards)- is not supposed to Establish religion. Any taxpayer funding of such a course would be unConstitutional, if it taught Bible study in the usual sense. If it taught comparative religion, many parents probably would object to any secular rational evaluation of religious views.this shouldn't even be a discussion. federal and state do not belong in religion or schools, unless parents agree 100%, our tax money must go to schools that we choose to send our kids to...our money should educate our children not indoctrinate our children to what our government wants..my tax dollars should go to private schools..and i am a child of God -not a religion
Second, your tax dollars should not go to private schools. School voucher schemes that allow parents to send children to private schools - especially with any use or teaching or practice of religion in them - are not Constitutional. One exception was made at one time,, for busing of school children to private schools, for the sake of safety. That is a more iffy question - one does not want students endangered by being forced to walk or to use old and unsafe vehicles. I do not think it is
Constitutional, but I would not regard it as a practice that has to be fought in the courts in order to have a completely pure interpretation of the First Amendment. There are more important priorities.
