Progressivism is, otherwise, a debilitating mental deficiency.
I think the author of the article put it perfectly when he described Progressivism as "...the political philosophy of sociopaths." I also think he hit the X-ring with "It is power-lust masquerading as a social theory, and merciless hatred for mankind dressed up as a new moral code." Gaffer, I've also noted how governments tend to jealously guard their "moral" monopoly on violence.
