Honestly I wonder how many women would have “grown out” of being tomboys if we had literally ever seen adult butch women on TV or in a movie or read about one. We occasionally get the little girl character who likes playing in the mud or catching bugs (which, don’t get me wrong, is great) but nothing after childhood. It’s like girls are being told, “we’ll tolerate this for a little while but eventually you have to be consumable.”
Not to mention so many stories that have that little girl character actually end up being about her “becoming a woman” and discovering like “hey femininity isn’t all bad because boys”
