First, I think your coffee is better than mine. Those are solid thoughts.
Second, I think a deep dive into the data around people's reactions would be illuminating and also likely disheartening. From an anecdotal perspective, I have people in my life exhibiting bizarre and illogical reactions.
Abandonment is an interesting theory. I think that could account for a lot. I think some of it stems from not wanting to address the ugliness in ourselves. We can all be small minded at times but bringing someone else into account for that forces us to recognize it in ourselves.
I definitely need your coffee.
