A good piece on this subject, especially as it relates to the "wall of separation" -
"Clearly, *what Jefferson was describing was not a rigid barrier between faith and public policy, but denominational allegiance by the state. As the Constitution says, the federal government was not to 'establish religion,' that is, to select a particular denomination as a national church. That’s all the wall is."
So why are so many academics opposed to teaching students in public schools the facts?
*Jefferson's response was actually addressing the government's potential danger to the church, not the church's threat to the government. Neo-liberals, secularists, and statists have turned the phrase and its intent on its head.
