What is the thing that most humans were inclined to do?
What is the common pattern that was observed around the age of adolescence when it comes to forming thoughts?
The answer is pretty simple.
Bigotry, or zealotry.
Lynch culture.
Two terms that could be best to define the common pattern.
When it comes to young people or people who have yet to form their own thought processes and values, it is rather easy to impellent some general thoughts to their minds, using the possible special triggers for emotional overflow.
For instance, when a girl of any age was said to be assaulted by a man, society would immediately take action, as the idea of protecting a woman had already been implemented in one's mind from the day they were born.
The same can be said when it comes to theocracy or religion.
