There seems to be this progressive instinct to claim that it's not enough for people to believe the same things I do, or support the same people I do, but instead everyone must always denounce the people I do in the ways I dictate or be shamed and boycotted. This instinct is divisive and damaging, and drives away erstwhile allies.

Posts like Pao's and this one, which are intended to enforce a progressive orthodoxy through the application of massive negative pressure, are far less effective in winning over converts than its authors suppose. A lighter touch would be far more effective.
