If you live long enough, you will be able to count the number of occasions on which enlightened and progressive opinion has reversed itself. In the most haphazard count – my own scattered recollections – we have gone through the following opinion changes in my lifetine alone.
Homosexuality is sinful to gay is good and natural.
Race is a meaningless ideological contruct to biological differences matter.
CO2 engendered by fossil fuels will engender a climate catastrophe to who cares about global warming, let us use nuclear fission- note: this one has not yet happened, but wait.
Soviet Communism in Russia is a permament part of the European power balance to [poof!] the whole regime collapses within a year or two.
Of the changes mentioned above, perhaps Communism was the most important geopolitical event. People born after 1990 can have no conception of the extent to which the 20th century was held in thrall to the idea of planned happiness through the elimination of private property and the centralization of decision making in governments, and of all power in the Bolshevik revolutionary vanguard.
I was reminded recently of how central Europeans, those whose countries had been occupied by the Soviet Union after WW2, were disbelieved when they insisted that the whole scheme was a construction of tyranny that would fall one day like Sauron’s tower of Barad Dr: instantly, into dust. The emigres insisted it was built on a lie, that nothing it said about itself was true, and that it was maintained by Soviet force and police terror. I can recall the disbelief with which such views were entertained in polite discourse in the 1970s. But the Lubor Zinks and the anti-Soviets were exactly right.
You can arouse similar feelings of outrage and disbelief by posting pictures of snowfalls in April to social media and complain about the absence of sufficient global warming. The response of the Karens, male and female, is immediate.
In your opinion, what other major social beliefs are likely to be reversed in the next twenty years? Discuss.
