Huh? I am not sure where you are from but in and near large cities in the USA in the Northeast and West Coast both before and after Stonewall things were open, but most bisexual and gay men even those who were "out" until very recently were very discreet, and it was fine for European white bisexual and gay men and women to be out, but not for blacks, Hispanics/Latin Americans, Arabs, people from Levant, or Asians and in many countries and in these cultures it is still like this today.
Despite TQ revisionist fake historians' claims the "lavender scare" of the 1950s and early 1960s was over-exagerrated, the only people who were ever really at risk were gay and bisexual federal government employees, military/intelligence personnel, and Bruce Wayne like sex addicts addicted to cruising and public sex who had no idea how to be discreet and keep their sex life seperate from their public personal life.
I am friends with a bisexual author who was in both NYC, Philadelphia, Baltimore/DC, and later SF and L.A. both before and after Stonewall. He agrees with me and said how being bisexual or gay then was basically like being a marijuana smoker when it was illegal everywhere, and that the "oppression" narrative is exaggerated as the only thing gay and bisexual men were really struggling about was to find other out but discreet bisexual and gay sex partners and have sex with as many men as possible.
My father who is almost 90 worked in Philadelphia in the early 1950s and long before Stonewall with out gay men both in a corporate business in an extremely large national company, and of course in theater. Everyone at this very large company knew my dad's co-workers were homosexual and lovers who lived together. Of course they were open and would separately but discreetly cruise the bars, sex saunas/bath houses, YMCA, public gyms, theaters/cinemas, and city streets for other men to have sex with.
My parents are not homophobic or biphobic, they are heterosexual like the vast majority of the population of people are.
If you are not from here or were not alive then you wouldn't really know what it was like.
