Considering that online schools are accessible coast to coast, there is not one christian that has an excuse for abusing their children with a public school.
Schools need to be privatized into a private system and/or parochial system ideally or at the very least, let the local community control the schools. The Feds should not be involved in education, it is one of those things left to the States, locals and/or the people themselves.
Online schools teach liberal doctrines too ya know. Although at the same time, they are helpful to avoiding the massive debt pile though.
