You’re missing the point. If a woman is unarmed, for whatever reason, would this be a viable alternative.
I think yes but it does have some risk.
I think I mentioned not being an authority on unarmed self defense. The only self defense advise I am qualified to give is: “buy a gun, learn how to use it, carry it”
But...The fact that a woman is being raped means that she is in a situation where someone bigger and stronger than her thinks he can get away with raping her. I’m thinking that would also cause him to think he can also get away with causing her great bodily harm. If she doesn’t have the tools, training, or whatever to win a fight, or at least get away, maybe fighting is not her best option great option. As to whether it’s reasonable to expect her to be able to bite him forcefully enough to incapacitate rather than just enrage him, I have no idea.
