It DOES matter if he ends up in a woman's prison. How vile to suggest it doesn't. Why would you want a dangerous paedophile locked up with women?
To answer the various people who made similar comments to my previous post, my personal belief is that the important thing is that the offender is in prison, i.e. not on the streets. That way their potential to find other victims is restricted to fellow criminals.
I don't particularly want "a dangerous paedophile locked up with women" - I just want a dangerous paedophile locked up, end of. It's not like (s)he's being sent to a young offenders institute, (s)he'll be with adult prisoners.
Prisons - male or female - are not "nice" places, neither are they supposed to be. They are full of abuse, bullying, coercion and intimidation. They're more like Time than Porridge, weaker inmates will always be targeted by stronger ones. Moreover, they're full of criminals. That's why I don't really worry about a transman ending up in a male prison or transwoman ending up in a female one, if they continue to offend inside their victims will be fellow prisoners rather than innocent people.
I think it's quite offensive to imagine that female prisoners are somehow "nicer" than male ones. There are a lot of appalling female criminals, Rose West for example, doesn't strike me as deserving any additional protection from someone like Goodier than Wayne Couzens does. It's also frankly misogynistic to assume that female prisoners are inherently weaker or less capable than their male counterparts.
I accept there needs to be a debate as to the extent to which prisoner-on-prisoner crime should be tolerated, but I don't think it's as simple as arguing male-on-male and female-on-female abuses are OK but female-on-male or male-on-female aren't. The idea that a transwoman has to be kept out of a women's prison implies that it's OK for TW-male or male-TW abuse is fine (as is female-female). There's a reasonable argument that prisoners shouldn't be allowed to abuse one another AT ALL, regardless of the genders of the perpetrator and victim but I disagree it's right to allow some abuses but not others as many seem to think.
