Statistically speaking, that's just not true. Men outnumber women by a LARGE margin, like ******* huge, when it comes to being victims of violent crimes committed by strangers. Offcourse, we are being more protective of women, so we have no idea of knowing whether the difference would still be so big if we treated them equally. That being said, we do live in a society where we are more protective of women, so your daughter on her nightly outing will have the neighborhood aunties keeping an eye out, your son won't, bystanders will be more likely to jump in at the sign of trouble for your daughter, not your son, she will be more likely to get any type of aid over your son and will be considerably more safe then your son. Offcourse she's more at risk then him for rape (and that is what we are actually worried about), but stranger rape is the rarest type of rape (at about 7% of all rapes) and is on top of that typically by a serial rapists, so in most cases you would be aware of an increased risk of danger. You know when you should be worried about your daughter getting sexually assaulted? Not when she's running around at night: when she's having a sleep over at her friend's house. Outside? She's much safer then your son.
