Do tell how much you know about the three theistic religions you mentioned and how most of them preach kindness and acceptance and those that don’t accept are going against the major teachings of their religion.
Faith isn’t pretending to know things you don’t know. It’s BELIEVING in something. BELIEVING (ie having faith) in something is FEELING something is true and acting upon that feeling despite having no proof. KNOWING something is having proof of the truth of something and has nothing to do with acting upon the truth of it.
