"Wont someone think of the (lots of?) women?"
Honestly: how are you defining "a lot" here? A dozen or two? That's a vanishingly small proportion of humanity, my friend. And would you even hear the tales of those who travel the world and don't get killed? I am just saying that you are making a big claim, but provide no evidence.
Or would you have us believe that a certain number of these kinds of murders are OK, because they're just "rounding errors" or "edge cases?"
What's the over/under number?
Negligible odds of death I'll buy, but a very large number of my women friends over my life have been sexually assaulted (and probably far more than I realize, it's not like it's something you bring up during holiday dinner). I'm often shocked by how few men realize how prevalent this is.
The idea that "women who aren't comfortably traveling the world alone depending on the kindness of strangers are living a life ruled by fear" seems naive at best.
Even back in the days when hitchhiking was much more common you would almost never see a single woman by herself, for good reason.
My original point still stands: the commenter made a big claim: world travel is (more) risky for women (than not world travel), but provided little evidence to support said claim.
And it kinda takes the fun out of such a trip if you have to be on edge in order to protect yourself all the time.
