There’s scientific truth – often absolute. But then there is truth with people – social truth; that’s different.
People have different experiences from where they stand, thier culture, their education, what they went through, what they saw and how they processed it all as only they could.
Trying to make people wrong about their version of the world is would not be very effective and likely a futile, frustrating, lifelong endeavor.
What you can do for a very small number of people is create great experiences that help or serve them, and they will begin to add those interactions to what they already had, and start to change their ideas and beliefs about how the world is.
