@XXSpadeMasterXX,
I agree that most popular theistic religions and sub-religions teach that all humans have purpose. They are not all egalitarian however in the "amount" of purpose each human has.
Their is some difficulty with non-theistic religions because they do not
necessarily place a
de-facto value upon human purpose.
EXAMPLES
Satanism (actually a non-theistic religion, they don't believe in Satan) does not necessarily place an inherent purpose to all humans.
Some versions of
Buddhism are non-theistic, however, and do place an inherent purpose in all humans, and in fact in all beings.
Please don't take those two examples as some sort of equivalence.
They are meant to show the
contrast in the spectrum of non-theistic religions.
