They'll just "de-transition." Plenty already have, after the initial high from the trendiness wore off. Same as any other fad. The big difference with this one I guess, is that those who were dumb enough to get hormones/surgery might have permanent consequences that can never be addressed. I guess those will be really depressed and/or rope. Unfortunate, but nothing to write home about in the grand scheme of things human societies go through. The interesting angle will be when they start suing the doctors who let them do this shit as minors.
You'll know we're in the proper backlash phase when said lawsuits start really hitting the mainstream discourse. In a twist of irony, gynocentrism might actually help pull us out of the trans insanity, because young women going to court and telling their sob story might be the thing that could finally sway otherwise immutable normies to finally realize how fucked up the tranny shit is.
