Bike commuting is a great goal to have and I really wish more people were doing it...However, making bike commuting into some extreme ideology, where you start preaching to people and forcefully trying to make converts out of them is not good...many years ago before I started bike commuting I was very car-centric, and now I am a car-free bike commuter. Nobody influenced me, nobody told me to bike commute, it was my own decision.
