The other day I went to the wedding of the son of a good friend of mine and one of the bridesmaids (I think it was the bride's cousin) was a manly looking woman with short purple hair that honestly made me wonder if she wrote for the Mary Sue, Star Wars, or worked for a video game company or Marvel/DC.
The actual ceremony was no more than 25 minutes and I couldn't help wondering why she couldn't just wear a dress (of course she dressed like a dude and stuck out like a sore thumb amongst the other bridesmaids) for that little bit of time. I said a prayer for her because she is young and maybe one day she will realize that she looks silly trying to act like a man.
I remember when I still worked in HR the first time I came across the phrase "gender non conforming" or "doesn't conform to traditional gender roles". This was like 07 so I didn't think anything of it, but I never would've imagined it would get as insane as it has.
One of the factors is that the scientific establishment is entirely weak or complicit. The queers have subverted enough of academia that they can always quote some "expert" or study that claims to support their position, which the media amplifies to claim that us chuds are anti-science, after having conditioned the public for decades to "trust the experts". They spout plenty of mystical bullshit too but when challenged they shift back across the moat to some position apparently defensible by research. (usually from fellow queers in the "soft sciences", and often via misrepresenting conclusions) Without that appeal to authority to fall back on I'm sure they'd try another method of control but it would be that much harder.
In other words we have a fundamental flaw in modern society and its epistemology/acquisition of truth, rather than a simple overton window shift that can be solved by shifting the other way.
