Is personal faith a debatable topic?

Back on Topic:I started a thread a few weeks ago about the Sacred vs. Profane as it relates to Emile Durkheim's social philosophy theory; it is near impossible to debate a person's faith.Personal faith is securely established in the sacred domain. As long as its tenets remain in the sacred domain they will be untouchable by science, which resides in the profane. The only way that I can see personal faith becomming debateable is for testable regions of the faith to be transitioned from the sacred to the profane. This is a slow process.*NOTE: Sacred/Profane is not Good/Evil. It is "Things required by religion/Things neutral". Sacred things can be good or evil. Profane things are just neutral.This is one problem with an open forum like this, creationists are hit from more than one angle at all times. As long as they feel that their faith - the "sacred" - is threatened they will continue to shut down to any logic and evidence - the profane (example: Buzsaw). The only way I see to change this is to slowly, gently and logically remove certain tenets from the "sacred" and place them more rightly in the "profane."Ex: Does man's body reflect the "image of God" as described in Genesis 1:26?If yes, then the "image of God" is corporal/physical. And if so, due to the diversity of the human race some people must be physically more like God than others.Since this is both an illogical and heretical stance it is imperative that the "image of God" is not a physical image. In fact, almost all christians would claim that God is not physical but rather spiritual. Therefore, the image of God must also be spiritual and have no relation to our corporal bodies.Now, with most YECs the literal interpretation of Genesis is deemed "sacred." Nothing from the "profane" (science, history, etc) can alter their ideology that Genesis must be interpreted as exact historical events. They have placed their entire theology on this requirement. They claim that in order for christian "salvation" to make any sense there must have been an actual Adam and Eve and an actual snake and an actual apple. No amount of profane evidence could sway them from changing thier "sacred."
