Here is where definitions get in the way. For the scientist, the term "faith" has no bearing on a scientific theory such as gravity or evolution. The theory is nothing more than a model describing observed phenomena and related facts.
OTHO, there are many that view a theory of science in the very same way that faith is viewed.
Thusly, the arguments get heated because the scientist is promoting a pure natural view of the theory whereas the non-scientist is adding a faith component to the theory thusly tagging it as anti-God or bigotry.
Methodological naturalism does not get an upper hand on the Religion Forum, it gets an even hand.
Kinda like the Mormon's definitions of a lot of 'christian' words seem to mean something else in their context.
