This has nothing to do with the demonisation of masculinity. Plenty of these guys are ultra macho before they transition, one of the main careers they have is the military. Rather they love extreme gender roles.

It's a fetish gone too far, nothing to do with anything women have done. There were guys doing this shit in Victorian times. And they have been trying to attach themselves to any progressive movement they could to gain power since then as well. Feminists actually kicked them out in the 80s which is why they set their sights on the LGB movement which kindly allowed them to take over their orgs completely.
