Oh this is something I guess I should explain

When I talk here about “bluehair moralists” it’s a pun

Like the one meaning is SJWs with “problem glasses” and brightly-unnaturally dyed hair

The original one I’m alluding to, old white-haired women used to get “blue rinses”, and this was used as a symbol of the restrictive anti-sex/fun morality of the obsolete pre-60s culture that the “counterculture” was fated to righteously do away with
