More Magic Words: "OK Boomer" Hits The Social Justice Trifecta

TIL "OK Boomer" are the new Social Justice "magic words", having lately been used to shut up heckling in the New Zealand parliament. As usual, Urban Dictionary has a mess of similar definitions, but all of them, it seems, hit on three things generally critical to the Social Justice mindset:

1. It purports to shut someone up, generally without engaging their arguments, whatever they may be.
2. It allows the user to silence a person based on innate and immutable characteristics, i.e. their birthday.
3. It grants the user a moral righteousness for themselves, and contempt for the other, based on the speaker's identity, i.e. how could you possibly know what it is like to be me because my life is so much harder than yours.

 This damned locution cannot die fast enough.
