Origin of 'to call out', meaning to decry

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?

[EDIT]

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.

The OED includes the 1981 date as the earliest attestation of this specific sense of call out, but it also cross-references call on which was used earlier in a similar sense. The earliest attestation of this use is from 1944.

You could (and should) promptly ‘call’ him on it and ask him to prove it.

This sense of "call on" is cross-referenced to another sense of call pertaining to gambling.

(c) trans. fig. and in figurative contexts. To accept (a person's) challenge or offer; to challenge (a person) to fulfil a declared intention. Also with the challenge or intention as object. Cf. to call one's (or the) bluff at bluff n.2 3a .

This series of cross-references suggests to me that there is likely a connection between the earlier gambling expression "call," meaning to match someone's bet in a game of cards, essentially "challenging" their hand, and the modern expression "call out" meaning to challenge someone publicly. The gambling connection doesn't completely explain the "out," which I would attribute to the tendency for this expression to mean that someone is being "exposed" or challenged publicly.

To call out seems to be a hybridization of two historically related idioms: To call to account and To call out.

According to English Idioms, by James Main Dixon, ca 1902, pp39-40 :

To call to account - to censure; to demand an explanation from

To call out - to challenge to fight a duel

There is (often enough) an aggressive quality to the habit of calling people out, making it fairly obvious how the two idioms may have naturally merged to become the one that was historically the most terrifying.

The only certain way to get a precise and certain answer to this question is probably doing a lot of textual studies using bots and older books, but my impression would be that there is little difference between previous uses of "call out" and the current-day use of "call out". It would not seem far fetched to see the evolution of "calling someone out" that is, calling attention to others about someone's behavior or calling attention to that person about his/her behavior.
