But it turns out that stereotypes are so obviously true that leftists found themselves in an unsustainable war with observable reality.

From the beginnings of the "modern" left, they have always been at war with reality. And proudly so. Anything and everything from the Jacobin's metric timekeeping to Stalin executing Khondratiev for stating economic reality to modern tranny shit is the same thing, from the same source.

Hatred of reality and Truth, because their doctrine is lies, issued by the father of lies.
