I feel your frustration- and, in fact, have just written a short piece about needing an answer — a diagnosis- closure in order to move forward — albeit from a different perspective.
The short answer is that we cannot change other people — we can only change ourselves. Living authentically — simply and kindly will do two things:
Enable individuals to live a good life, well.
Lead by example to create meaningful communities that together could enact real change.
In other words — stop waiting for the answer from someone else. Everyone else is doing that!
You write well — step up and lead with your pen.
There are worse ways to make a difference.
