"Tara still has a penis, that puts the women inmates in a very vulnerable position."
I dont' accept that having a penis makes someone dangerous. Plenty of crooked Tories have penises. I would feel safer sharing a living space with someone like Johnathan Aiken or Neil Hamilton than Tara.
Rape does not necessarily require a penis. Tara has shown that she is dangerous by her behaviour already. She is in jail for a violent crime: assault.
And it will be impossible to even have the debate about balancing the potential harm that could be inflicted on Tara by being housed in a male prison, with the potential harm that could be inflicted by Tara, a convicted violent offender, on other vulnerable women if housed in a female prison, because to attempt to do so is deemed "transphobic".
Tara is an individual and a risk assessment has to be made based on her personality and history of bad behaviour. I feel that the best place to house her should be decided by prison officers, pychologists or maybe a judge.
