Many people who may have "Free Will," seem to suppress it by"Beliefs."
Belief, is accepting something on faith or trust without having scientific proof or even "Prima Facie" evidence to support that belief.

Therefore, if you present a particular belief as a fact, when it cannot be proven as such, then you are actually promoting a "Lie." If you doubt that assertion, then look up every definition of a "Lie," that you can find and compare it to the "belief."
