Well, specifically the plot is that she was gender surprising everyone on the force. The ending reveals that her gun had dug into everyones hip at one point it would seem.
Writing her as that kind of person is definitely demonizing trans, but their reactions were the normal overblown homophobia of the time. Not trans specific. It wasn’t just the idea of her being trans causing the reaction.
Also, the implication at the end is that she had been fooling around with many of them and they were all just realising her gun wasn’t digging into their hips either. It’s not just recoiling at the thought of a trans-gender person.
In real life, it’s normal to not ‘surprise’ someone with your gender. They should know full well and be accepting of what they are going to find long before it is revealed.
Of course writing her as having tried to trick most of the police force with her gender is for sure demonizing trans, and was also a ‘fear’ at the time. Like somehow trans people are doing it to ruin other peoples lives, instead of stop their own from being ruined.
Outside of that, it was the normal overblown reaction to homosexuality that was common at the time. Just in real-life cartoon style, which was Jim Carreys shtick. Plunger to the face is very much how a cartoon character would try to clean something off their face. Except it would probably pull their whole face off leaving it blank and they’d have a floating pencil draw a fresh one on.
That’s interesting, just looked it up assuming I had likely heard the uncensored version at least once in my life, curious what could be removed from it. But yeah, turns out I have never once heard the full version. That is a very good example.
