We’ll worry about where they’re incarcerated when they’re tried and found guilty. Until then it’s all hypothetical in this country.
It's not just this though is it? It's police information for suspects being accurate, it's crime records being accurate, it's victims not having to comply with the Equal Treatment Benchbook (written by AGPs it seems) being forced to call their rapists "she" in court, it's victims being able to access single sex therapy. All of those things have to be in place before you can sit from a position of detached luxury, hand waving it all away "oh we will will about the end stage THEN". You won't get to that end stage with self-ID.
You can try to pretend this isn't fundamental to feminism but it doesn't wash. This is why TRAs hate how we've been successful in so far resisting the worst ie the Canada situation. Don't dismiss this. It's mission critical. Not moving to self-ID is a massive achievement of grassroots resistance. Don't minimise this and don't underestimate the determination of those who will continue to push it and the grave threat it poses to women, children, and the truth.
