They likely already were facing a lot of bullying. I’m old enough to remember people claiming that being gay meant you could give people AIDS from a toilet seat. I had a Health textbook that described “gay bowel syndrome” as a chronic condition caused by intimacy. Nevermind the teacher-sponsored religious groups that talked about how sinful it was to express any kind of affection towards one another. Just enormous amounts of misinformation, fear, and hate. And if you were a singular Out voice, it all got directed at you.
Clubs like this are as much an immediate defensive measure and emotional support group as a long-term progressive spearhead.
Which isn’t to say that spearheading the project doesn’t take an immense amount of bravery (and hard work and some exceptional social skills). But I think it mistakes the pre-organized LGBT community as somehow enjoying security through obscurity, rather than a population that simply suffered in silence.
