Look, just because cyberpunk, Robocop, Demolition Man, Brave New World, and 1984 all managed to simultaneously become real doesn't mean EVERY grimderp future can be so lucky.
You forgot to mention Animal Farm (and Idiocracy to a lesser extent) but otherwise you're dead on the money.
Yeah, I'm not entirely sold on that. The gay community wasn't listening to ANYONE when it became clear the bathhouses were a focal point for infection. But no, the stupid butt-fuckers had to have their gay old time instead of keeping their pants on for a while.
The title of the book may be 'And the Band Played On' but it's not a reference to government inaction -- it's a reference to how the community blew off all the warnings.
The AIDS epidemic was caused by both government inaction and gay apathy. To understand why the gay community was as foolhardy as they were during the initial epidemic, you've got to understand both the hedonism of 1970's gay life that allowed the AIDS pandemic to happen in the first place and the bitter repression of the pre-Stonewall era that came before that.
Before Stonewall, there was no real organized "gay community" for the most part as homosexuality was considered a crime in most states and even in the few places it was legal or quasi-legal, it was severely stigmatized.
There were small communities and illegal gay bars in major cities if you knew where to look, but even if you were living in somewhere like San Francisco or New York City, you might not know where these places were as there was a lot of secrecy and it was all about knowing the right people. A lot of gay men back in the 1950's and 1960's were alone and isolated, and you had a lot of gay teens around that same era who felt even more alienated.
Even the gay nightlife that was there in the 50's and 60's was fairly mundane and sedate. Your average gay bar would be like a normal bar, save for the occasional drag queen or leather dude. Even the fucking leather community were just gay bikers and veteran associations back in those days (the so-called "Old Guard") and the Stonewall Tavern itself was seen as one of the seedier gay bars in New York back in the 60's. Gay bathhouses were even fewer and farther between than gay bars and were actually looked down on by the gay community in the Post-WWII/Pre-Stonewall era
When the Stonewall Riots happened, it actually was a big deal for the gay community. Similar organizations appeared for the lesbian community and the transgender fringe, and this all sort of coalesced into the modern LGBT Community in the early 70's.
Another thing that happened in the early 70's that was even more important than Stonewall was the DSM-III removing homosexuality and bisexuality from the list of mental illnesses. This was more important than even Stonewall was, since it led to a lot of states and localities decriminalizing homosexuality.
Naturally, you saw the rise of bathhouses and gay bars became a lot more shady and party-hardy. The bathhouses went from being a dark place of ill repute to the centers of the gay community in major cities during the 70's.
Of course, this all tied into a wider cultural phenomenon of hedonism and sexual promiscuity in the 1970's. There was the Sexual Revolution, The Golden Age of Porn, and the "Free Love" of the 60's counterculture finally going mainstream.
The gay community in the 1970's was basically a distillation of the wider sexual culture norms of the time.
Since gay men don't get pregnant, nobody wore condoms. It was the norm to go bareback since most STD's known at the time were often easily cured with antibiotics. If you caught syphilis or the clap at some bathhouse, you'd just go to the doctor, take some antibiotics for a few weeks, then go back to the bathhouse to have sex with anything that moved.
Because HIV has a notoriously long dormancy time with no real symptoms, a lot of people in the second half of the 70's were infected and didn't even know it until they were showing the symptoms of full-blown AIDS, and by then they had spread it around to everyone they were sleeping with. AIDS was one of those black swan events that nobody on either side was able to predict with the knowledge at the time.
Remember, this was also before the internet. Even after AIDS started getting noticed in the early 80's, there was still a lot of misinformation, misconceptions, and downright confusion even after the virus and its modes of transmission were discovered by the CDC.
AIDS was often referred to as "gay cancer" in the early days because the earliest known victims were developing rare skin cancers seemingly out of nowhere. A very common misconception from that time was that the cancers came from overuse of certain party drugs such as "poppers" and the virus still spread like wildfire.
Nobody wanted to believe that the party was over and that AIDS meant that they couldn't keep clinging to the hedonism of the 70's. It didn't help that Reagan was president and was popular among the Religious Right. A lot of gay men often dismissed the warnings of government officials because they were either in denial or thought there was some ulterior motive to closing down the bathhouses.
The history of the AIDS pandemic in America would be a comedy of errors were it not so tragic.
