All interesting replies.
Interesting thread indeed.
As a general rule, I look at the world I was told was reality. Then I model a world in my mind, where billions of individuals, some quite smart, some quite immoral, and some quite bold, all have operated with aggressive self-interest for thousands of years, to the point of actually gaining the reins of power at times and being totally immune from consequences.
If you compare the two models, you will realize most of what you have been told is reality today should be utter bullshit.
If that helps.
