The ordinary meaning of the word 'faith', as in e.g. 'John has a misplaced faith in his own abilities'.
Using faith and belief interchangeably seems disingenuous and ignores the religious context that is part of faith. Faith implies a lack of compromise, a concreteness, and unwillingness to change. Using that term to describe evidence based science, and the belief that evidence ought to be presented before a belief is held is an attempt to reduce science to dogma.
What you describe is more like fideism.
