Due to the wide spread of dehumanizing each other over opinions that are not reasonable to us, I sometimes get the idea that accepting others opinions that are not reasonable is almost beyond the human capacity.
Few individuals can survive cognitive bias, cognitive dissonance, egos, exposure to different versions of reality, their culture, their insecurity and their lifelong conditioning to humbly and peacefully accept what is appeared as unreasonable for them.
The problem gets worse with those who take bride of their intellect specially when taking pride of one's intellect stems from that everything is already known and no need for further investigation.
