Yes I meant the Victorian model of social progress
Roughly 1870 was where Italy and Germany united and nationalism was all the rage. Discarding regional identities in favor of the New Italian, German, Briton, etc was the big push.
What I'm saying is in that scramble to define what was an ideal citizen, think of the Scout oath. They wanted thrifty, productive, obedient, predictable souls who played the game without bucking their employers, the government or Church.
Heterosexuality was assumed as the default state and no overt provisions made for acceptable homosexuality in
adults were ever made except possibly in older "companions" for nubile women to keep them virgin until marriage and of course the Catholic Church's *cough*"celibate" *cough* orders.

People with options (money and/or isolation) typically could do what they liked. That option disappeared as more and more people had access to and communication with more "cosmopolitan" influences, thus flattening out a lot of regional differences.
If you think that's tilling a fertile ground for fascism, or at least reflexive jingoism-- you get a cigar or a rose, whichever you prefer!


Tolerance for deviating from that norm became traitorous, not just eccentric as it had been for centuries.
I've always been stupified by the pretzel logic in the US banning homosexuals from military service b/c they might be "security" risks. *facepalm*
Don't give the KGB or whichever hostile agents a handle to blackmail them with, you bozos!


It made me sick anytime somebody with twelve years's exemplary service as an effective soldier/sailor/marine/airman would get flushed in a divorce or lovers' spat where they got outed or some new CO would go on a rampage trying to boot anyone remotely offbeat, no matter how effective and dedicated they happened to be to look "effective".
Anyhow back to the assumption of heterosexuality as default/good state-
see my previous post- that's not news.
It's only when folks got pressed into cookie-cutter models of "proper" behavior that it became a source of ostracism and persecution for oddballs during spasms of religious or secular fanaticism about proper conduct e.g. English Civil War, Salem witch trials, and rise of nationalism during the late 1800's from which the great purges of Germany and Soviet Union birthed to rid themselves of whomever offended the new order, thus bringing utopia closer.
