"Our greatest role in relationships is to be a light, not a judge."
-Stephen Covey
We all have our own individual, unique light. It isn't our job to run around and shine our light in everyone's face, saying we are right about things and they are wrong. Everyone has different values and priorities, and different causes and fights they are willing to fight in a day. We can only be a source of light for what we believe in, and be a guiding light for those when they are ready.
Lead by example instead of telling others what to do.
