Note that those who want some religious doctrine to be taught in public school would be incensed at the thought of Wicca or any religion other than their own being taught. Islamics would not want Christianity or Buddhism to be taught, while Christians would not want any non-Christian religion to be taught.
Actually, it is more specific than that. Catholics would object to Protestantism being taught & vice versa.
BTW: My family (on father's side) have been Quakers since circa 1700. Quakers are very behavior oriented. They would accept an atheist as a member.

But what kind of cogent argument can be advanced for logical implication that isn't circular?
Logicians & mathematicians avoid circular arguments by including some undefined primitive elements in the axioms of systems of logic.
For example: Note that lines & points are not defined in Euclidean Plane Geometry.
