I think you're right Jacques. It's just a fundamental failure of basic English comprehension, not knowing what the word "hypothetical" means.
Assuming the hypothetical situation included miraculously keeping the nasty men inside even when in reality they're exactly the sort of men who would break the rules... I dunno, maybe you could put electronic tags on them or something. Those into dystopian fiction could maybe even go for some sort of Vox style set-up, though personally I wouldn't go for that because NAMALT, just some sort of tracking device to keep them where they were supposed to be.
Well, it would avoid the situation I encountered as a student.
Serial rapist on the loose. My male friend walked me 3/4 of the way home, wasn't that worried about the rest of the way, well lit, very busy street. Except there was a bunch of lairy drunken blokes (yes, I know women sometimes get drunk and lairy - but not in the same numbers, and the MoJ figures for numbers in prison by sex bear me out on this one). Then I got white knighted - to be honest, he set my spidey senses off worse than the drunks, but all that wretched female socialisation kicked in: here was someone offering to be nice, and there clearly was genuine danger up ahead.
Of course the spidey senses were spot on. Thank god for some swift talking and a pair of trainers rather than high heels...
But of course somehow I'd have been equally at risk from women...
Nope. The statistics just don't hold out on that one. 90% of violence against the person and 99% of sexual crimes are committed by... wait for it, wait for it, this is going to be a totally shocking surprise for some of you... MEN.
NAMALT, and all that shit. But enough of them to cause a real fucking problem in society.
And of course I don't really wish for a curfew - I'm a social liberal at heart who believes in individual liberty, freedom of movement, freedom of association. But it's still an interest thought experiment.
(Even if some of the hard-of-thinking round these parts can't grasp the idea of a thought experiment).
