Progressives claiming that right-wing authoritarians are irrational is like right-wing authoritarians claiming minorities are mentally inferior to whites. They both ignore basic biology. The human brain works the exact same away in every human without physical brain damage. This is well established by research over recent decades. So, these dehumanizing statements are just wrong.
Research shows that the various differences between individuals or groups of like-minded individuals are due to the ‘programming’ of the individual brains. This programming varies as each individual lives their lives and each life is greatly affected by circumstances beyond one’s control – until we leave the ‘nest’ and gain some control.
We do not chose our birthday (day, month, year, century, millennium etc.). We do not chose where we are born (field, house, hospital, neighborhood, city, state, country, world, universe, etc.). We do not chose our parents ( nurturant or strict-father; poor, middle class, or rich; drop out, high school grad, BS, MS, or PhD). We do not chose our siblings (none, older, younger, 1, 2, 3, 4, etc.). We do not chose our other relatives just as our parents had no choice. We do not chose our parents friends. We do not chose our K-12 schools, teachers, or religious leaders. Yet all these external factors greatly influence what we each became and how successfull we are.
If David Koch and I had been switched at birth, I’d at least be richer and he’d be poorer and worried about income inequality.
