JEFF JACOBY: Thuggish censors in the marketplace of ideas.

[T]his is what the marketplace of ideas is turning into. The ruthless determination not just to silence opposing points of view, but to humiliate and crush even allies willing to hear an opposing point of view, violates every liberal principle of tolerance, reason, and dialogue in the public sphere.

My take: the progressives are scared, very scared, that they're going to lose and lose big in the very near future. First they were ignored; now ther're being laughed at; and soon there will be anger.

Progressives don't do very well when anger is directed at them.
