The thing is - how are you supposed to know whether a person is LGBTQ+ or not in a movie? If they has no crush on a person of their gender or no nude/sex scenes or other relationship behavior - they can be anything YOU want them to be. There was nothing to say in the movie X was/wasnt straight or Y was/wasnt trans or Z was/wasnt polyamory. They are not treated as straight by default, they are NOT treated in that perspective AT ALL. And only the guys that feel a need of representation or are sick of other folk's getting representation make it a thing to speak of.

Edit: sure, it doesn't count for women or races/nationalities, but it's only because these categories cannot be invisible and hidden by the plot.
