Check your sources Plaidos and Korrasera (link) oh my god
I've gone over this before (link), but I'll copy/paste what I've already said as I go through the apparent sources
The Ciba Collections mention "assigned sex of rearing" (1948) in the chapter about about sexual differentiation, with that page being about (CW drawn nude diagrams) Gonadal Dysgenesis (link). It doesn't appear to be discussing trans people at all nor does it use coercive(ly).
The 1965 "source" uses transgender the "same year" it was coined (doubtful), mentions papers from 2007, doesn't use coercive(ly), and clearly states it is the 20th edition—which came out in 2008, unlike the 15th edition which came out in 1965. An archived version of the 15th edition, from the actual publication date of 1965, is available on Internet Archive (link)—it doesn't mention trans people.
The 2002 claim is so easily debunkable it's not even funny. You can read it here (PDF). At the top, one of the first things to be written is "2002 (updated in 2011) from Timtum: A Trans Jew Zine", which originally was published in 1999 by the same author. You can scroll to read the scanned page (29-)31 here (link) (edit, if not, it can be viewed here [link]), CAFAB is not used in the original (nor does it explain how it was coined)
Claudia Johnson (quoted in Cosmopolitan) is a relationship, intimacy, and sex therapist, and I'm unable to decipher how such professions would make her a reliable source on this historical information. There are a lot of claims made, but none of them have or are solid evidence.
The 2015 source admits they do not have a source. A trans woman has already come forward and claimed she coined it around 2009 (link) (original sources listed aren't trustworthy/time stamps aren't accurate, similar to Korasera's post).
AGAB, ASAB, DSAB are all phrases that existed prior to the 2000's. The acronyms didn't just suddenly exist. There was a history of figuring out the wording.
The earliest I could find "the sex they were coercively assigned at birth" was on July 3, 2010
Here is an excerpt from another Livejournal
“Coercively assigned” is another vital neologism [newly coined phrase]. It’s not just more syllables to the word ‘assigned’- which itself made headway against the reified naturalism of one’s birth and its meaning for gender- it is a term with political power that we had to bring into the conversation to illustrate something. Not only is the M or F on our birth certificates an assignment, but it is coerced. Parents cannot say no, (just as many parents could not say no to doctors who wanted to mutilate intersex infants and reconstruct their bodies), and you cannot say no, can you? The term “coercive” adds needed meaning that reveals the truth behind natal nomenclature and assignment: the truth of its constructed nature and its oppressive effects
This was from October 21, 2010
Which blatantly states how the C was newly added
This would be hilarious to me if it weren't something intersexist that people were taking as gospel
