Hard disagree. Or rather, faith, in anything, can be as you describe (a non-religious example being politicians), but it doesn't have to be (and shouldn't be).

Whether a person is optimistic or pessimistic in the face of unknown is a matter of faith. Values/morals, even outside of an organized religion, are still a matter of faith (not that they'll be rewarded, but that they're somehow better, even in situations you'd be advantaged by disregarding them). That there is value in life, in expression, etc, are all matters of faith, as for every bit of rational evidence that there is benefit in them, there is also rational evidence that there are issues in them. The fact philosophers don't end up in the same place indicates there are, at minimum, different axioms over what is valuable or necessary in the first place.

Whether faith happens to also include a concept of god is immaterial; most if not all of us operate under concepts just as immaterial but which nevertheless we believe in.
