Well, male as default is probably best expressed in the trans movement by males keeping and simply renaming their genitals, and females who wish to transition, or simply be 'non binary' feeling it necessary to physically bind their breasts or have them surgically removed.
I don't there's a much starker illustration than that, tbh. Even this daft video realizes that women pay the price of gendered inequalities, but their answer, like so many before, is to set up a special exemption route for the few, rather than an actual feminist response which would be to fight against the structural inequalities for all women.
This is why this is all antithetical to feminism and is, in fact, self serving individualist capitalism.
I commend this video from Magdalen to you as another example of this kind of self serving anti-feminist thinking. Ash Hardell got very whiny at Magdalen in response to this.
