Frank, it is inherent to human existence that there are different views on many subjects. Listening to each other, understanding and respecting each other is a commendable endeavor.
If I read your narrative carefully, this good practice is threatened to come to an end. If this is the case, fanatics and conspiracy theorists will get the upper hand and the world will become unbearable for everyone.
I hope your good illustration will contribute to the realization that we should prevent this.

Sadly, I have to agree with the observation. People have forgotten that there can be a variety of opinions. Not all are right but discussion of ideas is fine. Love your drawing. Here's hoping that people learn to listen again and not just question.

This illustration speaks volumes as does your narrative, Frank-well done!
