........ Honestly, this isn't too surprising with how saturated the media is with minority groups. Almost every show I see on various streaming products ends up having heavy LGBTQ+ plots rammed in, trans characters showin up, always a multicultural combo of characters and fewer and fewer generic CIS white people. When the media is constantly blasting you with minorities and minority issues, in a highly biased way, it's totally not surprising at all that people would start thinking they're a way bigger slice of the population.
Like someone once pointed out that there were more airplane pilots in North America than trans people. So imagine if every TV show you watched, suddenly had an airplane pilot show up and talk about airplanes a bunch, had whole episodes dedicated to his occupational trauma, regardless of what the main plot of the show may be. That would be more representative of the general public, than having trans people in every fucking show going on about trans trauma.
