This question discusses the use of "call out", meaning to publicly denounce or decry a person or a behaviour. One of the answers to that question gives an earliest known use of the expression from 1981.
I wonder how this expression arose? Is it an abbreviation or generalisation of an expression from a particular field of activity? For example, a teacher 'calling out' an unruly child from behind their desk, or whatever?
Thanks for the suggestions. Obviously, 'call' is a very basic/common verb, and there are loads of idioms involving it. There are various well-established uses of "call out" as well: one cowboy 'calling out' another for a duel; a tennis umpire calling "out"; "call out the guards" to quell a rebellion; and so on.
What I specifically want to know is which, if any, of the earlier senses of "call out" led to the modern usages - "call out [bad behaviour X]" and/or "call [person X] out on her [bad behaviour Y]". (I take it as read that the former usage is a contraction of the latter).
Example: "Always call out everyday sexism!"
Evidence that the usage arose 'spontaneously', without reference to any other sense of the phrase, would also be acceptable as an answer, of course.
