This is absolutely it. One of the offensive parts of the trans ideology is men who declare they are in "girl mode" today and are going to spend the day wearing a dress and baking (or cleaning).
I'm not even making this example up - I've seen a ton of tweets exactly along these lines. It's fetishising what it means to be a woman, and pushing us back to stereotypical male/female genders that were prevalent back in the 1950s.
While I have my reservations about some elements of trans ideology (men in single sex spaces eg), I don't really care how someone wants to identify. Whatever label you want to put on it, we're all either men or women and that's an immutable and irrefutable scientific basis. From there on, it doesn't matter. You're a bloke but want to wear a dress and lipstick? Crack on, happy days. You're a woman and want to shave your hair off, wear a man's suit to the office and play golf with the boys on your weekends? Good on you. It doesn't matter. Express your identity however you want, regardless of your biology. This is where society needs to place its focus, the acceptance of individual expressions of identity while still recognising that biology doesn't change.
And it's why I struggle deeply with non-binary, more so than I do with trans. You don't have to embrace gendered stereotypes to be a woman or a man. Androgyny has been around forever, and we didn't need a non-binary label back then to be a gender non-conforming woman. As for the men, look at Harry Styles. Regularly rocks up wearing women's clothing, sometimes even carries a handbag. Wears nail varnish or makeup. Women still drool over him. No one gives a shit that his presentation is very fluid. But he's still a man.
I don't understand the point of non-binary. It feels affected and attention-grabbing. Courtney Stodden is an excellent example of it all. Now identifies as non-binary and uses they/them pronouns but whose image is a heavily sexualised female with tiny clothing, massive fake boobs and provocative poses etc. I don't really care about any of that, but I fail to see how these two things align. As I said, it's about being relevant, attention seeking and in the case of teens, typically it's about rebellion.
