Just to be clear: women do not transition to men to level the playing field or materially benefit themselves.
Studies of post transition income show that trans women go down (sometimes drastically) whereas trans men tend to stay about where they would have been. You get benefits of being treated as male but then you have discrimination and other problems as a queer/trans person to balance it out. So while I can report on the moments when socially and structurally I am treated as a man, it isn’t the total experience if my life. I still am trans. There are significant problems associated. I wouldn’t reccomend it as a career enhancer. To say nothing of how unpleasant transitioning just in hopes of getting a raise would feel.
I agree with regards to masculinity.
Well there is plenty of tolerance for elon musk having zillions of only boy-assigned babies. So it isn’t the concept of sex selection that leads to being universally regarded as evil. What else could it be?
