TLKY,
There is a difference between Emunas Chachomim and treating Gedolim as infallible (what do you do when there is machlokes?). Emunas Chachomim means trusting the mesorah and trusting that the Chachomim are acting out of the best of intentions. It does not mean blind faith in what they say. They are not Neviim.
When you are in Yeshiva and the maggid shiur says a pshat that you disagree with, do you just accept it? I hope not, because if you do you will never learn how to learn.
