It's a horrifying dystopia, with ALL women second class, excluding perhaps a tiny wealthy and prominent minority of women who can stay above the fray.
This is such an important point. I earn my money in the "knowledge economy" where women can compete with men on an equal footing, and where my male colleagues tend to be very decent sorts who genuinely do see me as a fellow human being. It would be very, very easy for me to project this experience onto the rest of society and say "well, John now wants to be Jean and come to work in a dress, go Jean, live your authentic life, TWAW." And in fact pretty much I do agree with most of that, up to but definitely not including the TWAW bit.
Fortunately I have the imagination to see that there are situations where sex matters and women need additional protections - fairness in sport, safety in areas where we are naked and/or vulnerable, because men are bigger, stronger and much more prone to violence than we are.
The fact that I (due to luck and circumstance) lead a pretty charmed life where I am largely protected from these impacts, doesn't mean that all women lead such a lucky life.
