A TPM Reader who is an academic and asks to remain anonymous sends along this note responding to the Kipnis story. I think the point about the demographic nature of the battle, though certainly far from the entirety of the battle, is an apt point.
I will say that I'm under no pressure at my own campus or in my own field.
But the broader tension-- amplified by social media and blogs-- is very real. A lot of hurt feelings, as the establishment figures like Kipnis are liberals, even leftists.
And needless to say, the fight is as demographic as it is ideological. The insurgents tend to be younger, gayer, browner, more female, etc. Conversely, establishment figures tend to be older, more male, and more Jewish.
