[By “Leftists” I mean, of course, the full spectrum of Dhimmicraps–and their Bureaucrappic minions–and all others to the left of “mainstream” Dhimmicrappic thought, Academia Nut Fruitcakes–almost all of them in the “humanities”–and at least 99.99% of the Mass MEdia Podpeople Hivemind.]
In every aspect of leftist propaganda–from hardcore Marxist theory to anthropogenic climate scare-ism to social “welfare” policies–leftist theories have been tested in the real world and found to be fatally flawed. Whenever I view the real world wreckage of leftist cant, I’m reminded of a Robert Heinlein comment:
“One can judge from experiment, or one can blindly accept authority. To the scientific mind, experimental proof is all important and theory is merely a convenience in description, to be junked when it no longer fits. . . “
By any honest assessment, whether one were to use Heinlein’s metric for science or Popper’s or any other honest scientist, leftist thought is anti-science.
