Attitudes about gays and transgenders actually got worse coming from the 1960s into the 1980s. The sexual revolution actually created a generation far more open and accepting, and the culture that lead to things like the Satanic panic, war on drugs, and resurgence of patriotism and religiosity in the United States actually made things worse for gay and trans.
Indeed, and in a broader view, humanity has literally always had trans people as long as it has had a concept of gender. So “in the 80s” is emphasizing the cultural lie that acceptance is a recent phenomenon, when actually bigotry about it is the recent phenomenon. The 80s were certainly not an amazing time for LGBTQ folk, but Playboy at least would have been sex-positive and accepting.
So this isn’t a “stopped clock is right twice a day” situation, because sex-positive spaces and media would have been more reliable clocks than the culture at large, when it came to this subject.
