Let's see, so you're equating left-leaning social views with 20th-century communism, and assuming people dedicating their lives to the rigorous study of society don't do their job. Indeed, that is the kind of reasoning that directs both the author of the article as well as others who want to convince themselves they can find solutions to society's problems (or deny their existence) while being completely unwilling to actually study society first. Denialism at its finest. If the "reason folks" were as averse to math as they are to human beings we would have been reading similar unending tirades about why quantum mechanics is just illogical. It is the particular genre written by people who honestly believe their narrow view of the world combined with their self-ascribed intelligence is enough to reason about something they are not only completely ignorant about but actually lack any curiosity of. They will fight for their right to "reason" yet not learn (usually by ridiculing those who do bother to learn the subject first)!

Also, I find it a bit ironic that you call for taking lessons from 20th-century mass-movements considering that the article echoes others similar to it -- written by scientists -- around the same time of the Bolshevik revolution, and served to justify other movements with no better record than that of communism.
