Where should this dangerous rapist be imprisoned? Because if self-ID is fine by Labour then there's no other place to house this dangerous rapist because by their standards they are entitled to be treated the same as a biological woman.
If we're so dead-set on accepting people as who they self-ID as, why should he be imprisoned at all, when he could just identify as a non-criminal? Is it really that much more absurd than the current state of affairs? It's just one or two rungs up on the exact same ladder.
Even if we join the likes of NS and completely ignore/deny the needs and fundamental rights of female prisoners to serve their sentences in safety, I think it needs to be pointed out that, if you are a male rapist and/or other sex-offender, targeting female victims, then being put into a female prison is not merely a potentially easier punishment, but it is no punishment at all: it is actually a REWARD for your crimes. It's the equivalent of sending a convicted career car thief to live at Brands Hatch, with unlimited access to the big key cabinet, as a 'punishment'.
