It strikes me that if abortion is banned and criminalized then even more girls are going to see their bodies as an enemy of their humanity and opt out of puberty and into mastectomies and sterilisation.
With the American TRA and left-liberal emphasis on changing the individual rather than changing the world, I can honestly see women who haven't adopted any form of trans identity becoming a kind of third class of women. First class will be trans women - all the benefits of male privilege + fun, sassy, feminine and up for it, and never going to piss off their employer/boyfriend/sports career by getting pregnant. Second class will be trans men, who no-one will genuinely think are men but they will be given some credit for showing iniative in attempting to prove they have brains, abilities and humanity by trying to become one. Third class will be plain, boring women, who didn't use their agency to opt out of becoming a plain, boring woman so they can't complain about becoming a breeder and carer and grunt-worker, and in fact (unlike the special people) they and their Mumsnetty brains probably identify with it.
