How do you guys remember back to age 2??
Gay awareness started to happen with "glam rock" in the late 1970s. It was fashionable for men to wear makeup and be bisexual...if you were a rock star anyway!! That was when David Bowie became Ziggy Stardust.
There were lots of gays and bis in the crowd I used to hang with in the 1970s. But it was a crowd of actors, artists, musicians, theater people, and waitpersons (mostly the latter LOL).
I recently read John Schlesinger's reminiscences as an openly gay movie director. His movie, the X-rated Midnight Cowboy, won Best Picture in 1968. Some of the gay parts of the movie were excised or toned down but other parts were preserved.
