Careful, I am not meaning to validate or invalidate any existential belief, only the power structures built around that belief. ;)

You initially presented this as changing what is taught.  There is another argument that belief itself cannot be taught or learned.

All of this only opens up with an appreciation of philosophy, rather than religion.

But I know I take an extreme anti-religion stance. That stance is based on my beliefs, most of which are supported by my philosophy.
