I the the point of the thought experiment, but I do wonder if it, and other similar types of illustrative tools, are all that helpful in the end.
It will always come up against the problem of over-generalisation, which leads to confusion and confrontation (as has been amply illustrated by the heated discussion on this thread)
It makes the point well that women daily adjust their behaviour out of fear of being assaulted, and of course it is presented with the (correct) assumption that its most likey to be men that assault them. Fine... but it doesn't logically extend to the point about women being blamed for being assaulted, or 'taking the risk'. I'd say that is the more important fact, and more revealing of the pervasive and negative influence of the patriarchy. There might be better, more powerful ways to make that point.
The fact that violent crimes occur is surely a reason for everyone to adjust their behaviour? Men, typically being stronger and bigger than women, are of course more capable of defending themselves, and therefore a less desireable target. Its no suprise that women, therefore, are more scared. I'm only just over 5ft 5 and qite a long way off being a beefcake and have spent my life avoiding situations where there might be trouble. Including certain social space, pubs, clubs, routes home etc. Hell, I even cross the road to avoid other blokes if I see them coming. I don't say that as a 'whataboutery' comment, only to say that feeling vulnerable is a strong motivating reason to change one's behaviour. I confess I don't feel much sympathy for the main thrust fo the thought experiment... but only from a 'shit happens' point of view.
What really gets my goat is the difference in how I, as a man, may be treated or judged after an assault differently to how a woman may be judged. The idea that women are somehow culpable for being attacked is a festering, putrid boil on society. It is surely one of the clearest demonstrations of male privelidge and the patriarchy. I think its actually highly patronising, "ohhhh, you couldn't help yourself could you? you poor man... she was just wearing a very short skirt and you got carreid away didn't you? ah, there there, its alright, the nasty temptress has gone away now". Fuck that, and fuck the patriarchy.
