In my undergraduate days at the University of Washington (a long, long time ago), I enrolled in a survey political science class as part of satisfying my general distribution requirement. The instructor was the head of the political science department and described himself as a “reformed liberal.” By this, he meant that he had come to see the absurdity of many of the positions and beliefs of the left.
He made your point one day when discussing the communist revolution in Russia. He noted that revolutionary theorists had concluded that the revolution would fail unless the middle class bourgeoise was destroyed completely. Critics then pointed out that they, the theorists, were members of that social class and would be destroyed along with the rest. The theorists agreed wholeheartedly, saying it was necessary, even desirable for the sake of the revolution and the masses. The professor concluded by saying that the theorists had such devotion to their revolutionary philosophy that they were perfectly suicidal in advocating for its implementation.
The left/liberal you met was a direct descendent of those revolutionaries. As the professor would have pointed out, this is not political science. It is secular religion mascarading as political science.
Thanks for your insight bro. Now, I can understand where these ass hats are coming from. I think they are complete idiots, but I understand where they are coming from.
