Indeed.
Many of our societal structures are a reflection of our basic nature and instincts. I am not quite certain that the leftists pushing this break down of social structure are thinking about the long-term consequences of these actions.
Reminds me in a way of the Trofim Lysenko chapter in the 1930's-40's in the history of Soviet agriculture. Lysenko denied Mendelian genetics and insisted that plant species would pass on acquired characteristics, and there was no such thing as an inbuilt "nature." This pleased Stalin and the rest of the comrades, since they said the same about human nature: just build a different kind of society, and the result would be a new kind of man. Homo sovieticus.
Lysenko presided over, like, 22 major crop failures trying to grow wheat and corn on permafrost. Many, many people died. But it didn't become LEGAL to teach plant genetics in the USSR until 1964!
