Wouldn't be a bad thing for the GRA to be debated in parliament.
As Kirkup says, politicians have been shirking their responsibility to examine how the law is operating in this arena for too long. I would like to see questions raised about how convicted male sex offenders have been able to obtain GRCs under the current system, and how violent male prisoners with and without GRCs have been able to transfer to the female estate.
The Freddy McConnell court case needs discussing too - it's a prime example of the sort of legal and ontological absurdity that GRCs can create, demonstrating that they don't just impact on the holder (in this case, McConnell argued that a GRC gives McConnell the right to falsify their child's birth certificate, creating the dystopian fiction of a child born with no biological mother).
Maybe some bold politician might even raise the question of whether the GRA itself is bad law, and that legally conflating sex and 'gender identity' is what has created all these endless battles in the first place.
