Because men get into fights with each other, and we're wired to protect our women.

If you go by statistics on abductions and abuse, it's really women who should be more on the lookout.

Men are less worried about some guy jumping out of a bush at night. Just fight him and move on; women can't fight back the same.

Or theoretically possible: the risks are equally big for both genders but men tend to be on the lookout less so end up in trouble for often.

How is it even controversial that women are more at risk walking alone at night? This is ridiculous.
