There is no 100% guaranteed action that will protect against rape. Having mace, or far better a gun handy is the best. Just as important as the weapon is situational awareness. Who is around? Who is acting suspicious? I should avoid that area with the blind alley because I can't see in it. Do I trust the guy I'm with not to be a creep, and what is the fastest way to disarm him just in case?
Apply the above to what we know about DUmmie women. They mostly think guns are icky, so no immediate defensive measures. The guy they are with is usually a loser that breaks laws and does drugs, so no sense of character or else they wouldn't be out with them. DUmmie women are mostly on a cocktail of drugs, licit and illicit, so no situational awareness to speak of.
Oh, and go ask a rapist if he likes his mark to fight back. They don't. They also don't want to pick up a capital murder charge if they kill a victim, not that they care about the victim just the death penalty. So, against liberal fantasies, by all available means. Gouge eyes, bite noses, box ears, knee nuts, whatever it takes to convince the rapist that you are too much of an effort. Got a gun? Just show it. Rapists don't like guns.
