This comes out of 40 years of research done by primarily by men. Why on earth do you imagine that living in a culture that polices and bullies boys to act in certain ways and not act in others, some of which are antithetical to human nature, would be anything but massively harmful? And pretending like Johns Hopkins medical school is some kind of liberal think tank is grasping at the thinnest of straws. 🙄
I get that you've drunk the Kool-aid and aren't going to be swayed by science, logic, or reason, so I'll not waste any more time here.
