All I mean is that statistic is not relevant here. One in three men commit sexual assault over the course of their lives. That doesn't mean it's a third chance someone's going to do it randomly to a women in the woods.
Would you feel comfortable leaving your kid with someone who raped a child? Or someone who has said they would rape a child if there were no consequences? Or even being around a pedophile as a kid? Why do you think a woman would take their chances with sexually aggressive men? Because rapists are likely to be repeat offenders, on average rapists commit more than 1 rape and have more than 1 victim. "1 in 3 men are rapists or want to rape, but that doesn't mean all of those rapists or aspiring rapists will want to rape you specifically when there's nobody else around and no legal consequences for their actions" is a hard sell to women, just like "pedophiles don't always reoffend" is a hard sell to parents. Obviously pedophiles aren't the same as men willing to rape women, but I feel that analogy makes it a lot easier for men to understand the feeling – a woman doesn't want to be stuck with a stranger who has admitted they would commit rape if there were no consequences, or an actual recent rapist for that matter.
