1941, May 19: U.S. Army Surgeon General's Office: "homosexual proclivities"

Jonathan Ned Katz notes that this first reference to "homosexual proclivities" as one of the "deviations" that disqualified men from serving in the U.S. Army, also constitutes the first federal, state sponsored institutionalization of the secondary term of the heterosexual-homosexual binary.

According to Allan Bérubé in Coming Out Under Fire:

After the Army Surgeon General's Office had issued its own screening circular to induction station examiners and Selective Service revised Circular No. 1 to bring the two [earlier] directives into line, both screening directives for the first time included "homosexual proclivities" in their lists of disqualifying "deviations."

Bérubé adds:

The Army circular also listed "many homosexual persons" among those to be rejected because of "psychopathic personality disorders," whereas the Selective Service circular instructed draft board doctors to refer all suspected homosexual cases to the regional Medical Advisory Board psychiatrists for closer examination.[1]

Katz explains: without explicitly mentioning heterosexuality, apparently, the U.S. Selective Service installed that unnamed sexual ideal as that from which unfit men deviated. 

This was not only a new discursitve construction but a bureacratic ruling that actively threatend homosexual men and caused numbers of them to be rejected or dismissed from the U.S. military. It also, for the first time, installed an unnamed heterosexuality as the official, federal state norm.
