To be honest, I think a huge factor in this is that many people agree with DotJones that rape in prison should be part of the penalty for incarcerated women. They think the fear of being housed with rapists should be a deterrent to committing crime. They're simply not brave enough to say it. Credit to Dot for being willing to say it, even if she's never willing to reply.
To all of you who secretly think she has a point, I'd like you to actually think about your own interests, even if you don't have sympathy for female prisoners.
The photos show 'Isla', formerly Adam Graham. He has been convicted of raping two women, and his estranged wife has spoken to the press to say he abused her, including sexually. He is currently in a women's prison, while the judge decides on what length jail term to hand down. From what I've read of the case, this man is not going to get given a whole-life sentence. He's going to be released, and when he is released, he will assuredly be young enough to rape again.
Pay attention to this bit: I don't have the impression he has much to go back to in his life outside prison. He's been homeless or sofa-surfing for years.
When he's released, and he will be, he may struggle with life outside prison. He will stop getting fed everyday, he won't have a roof over his head, and if he's been housed in a women's prison all that time, he'll lose access to captive women to terrorise. He'll miss that.
He enjoys raping women and he has raped or attempted to rape three women that we know of. Prison is supposed to be a deterrent for rapists. However if he knows that he will be rehoused in a women's prison, he won't be so highly motivated to resist his urge to rape. In fact, he may actually be motivated to get sent to prison again!
Plainly put, that means, raping another woman (or two!) outside prison. You, or a woman you do care about, might be who he picks. So I suggest that you campaign to ensure that 'Isla' and other men like him go to men's prisons. When a rapist thinks the consequence of rape is being rewarded with daily access to a set of trapped women, it means he is aware he could get rewarded for raping you as well.
