Excellent preventative measures.
Now please tell me what preventative measures you have told your wife to employ against you in case one day you or another male relative rapes her in her own home, for example?
Since the majority of rapes are intimacy rapes, would you expect your wife or girlfriend or partner, to take self defense classes so she can take preventative measures against you? After all, if she is a responsible adult, then she, following your examples, would view you as a potential rapist and she would be taking every step imaginable to ensure she prevents you from raping her. Just in case. Do you feel comfortable with the knowledge that your wife is learning self defense just in case one night you can't take no for an answer? Does it please you?
Because preventative measures would mean that women would have to view all the men in their lives as potential rapists and taking all requisite precautions to ensure they do not become a victim.
As far as intimacy rapes are concerned:
Apparently, you are revolted by the idea of people being careful about their choice of partner or spouse.
Why?
Why is that you automatically jump to the conclusion "You're just blaming women" when someone advocates a more careful approach to the choice of partner or spouse?
Do you believe that if a woman feels she is in love with a man (or a woman), this means that she has the right to throw her brains away, and nothing bad should ever befall her - because she is "in love"?
It is my belief that most men would not enjoy the world they advocate. That is, the open-ended prevention theory is so sub- or un-consciously widespread that if it ever came true, men would be really pissed off at women for treating them that way.
In the end, the only functional solution is to stop presuming male privilege, whether it's because she accepted a date, or because she let him buy her a drink, or because she was walking alone at night, or because she agreed to marry him, or because ... really, what we're down to is two competing assertions.
And again, you are arguing against people who are not here.
Either women are human beings entitled to the same rights and expectations as everyone else, or they're not.
In which case, a charge of rape can only be prosecuted if there is evidence and / or witnesses, as is the standard legal practice in the prosecution of all other crimes.
