Not going to argue the legality etc. BUT
IT IS SAFER. That's an indisputable fact. Women are less likely to commit violent crimes, and if they do, are going to be easier to fight off.
How many women have been sexually assaulted by other women? By men? Knocked out by a woman's fist? A man's?
Try to quickly name 5 male and 5 female serial killers.
Before men complain about how this is discriminatory to men, maybe they should ask why women fear men in the first place.
And if your daughter were getting a ride from a stranger at 3am to a cabin in a deserted area would you REALLY feel she was just as safe with a male driver as,a female?
And please don't give me the "Not all men" argument.
