Because when you keep saying "people need to know how best to avoid being a victim of it" you are using victim blaming language, you are repeating arguments that have gone on for decades, and is ineffective and unhelpful and only causes victims to blame themselves on top of society that already blames them. You cannot mitigate rape by telling people how not to get raped.
No, I'm really not. I'm using sensible, rational language. If you find yourself in a location where people are very often <insert any crime here>, it's a sensible idea to consider how best to avoid being caught up in <aforementioned crime> if you're going to be in that location. Whether or not you decide to look up anything on that subject, if you're a victim of <bracketed words again hooray>, hey, you're a victim, shit happens. If you decided not to heed any advice on the subject, that doesn't make it your fault.
Is it possible you put yourself in a more compromising position than you might have if you'd been more mindful of the relevant risk factors? Sure, it's possible, but that's not the same thing as having invited an attack on your person. For all anyone knows you'd have ended up in exactly the same spot if you'd done everything "right." It's not your fault either way; it's the fault of whoever did the deed.
Maybe I'm just an overmasculine moronic man, but I don't understand the difference here between taking caution to avoid rape and taking caution to avoid anything else happening that you don't want to have happen. To me, just in theory, it's the same as all the other stuff we've listed previously in the thread. Whether or not there's a shit-ton of sexist baggage attached in the case of rape is irrelevant
to whether or not things can be done to try to lessen personal risk factors. It simply doesn't matter. The misogynist assholes are going to victim-blame no matter what the victim did.
An upstanding woman could have been wearing a burqa, defended herself against two assailants with a stun gun, blown her rape whistle like there was no tomorrow and screamed all the right words in seven different languages and there would still be people claiming she clearly begged for the D from those five guys who posted her violation on Facebook.
Because unfortunately, as far as I can tell, humans suck. We just have to deal with that as best we can, whatever form that sucking happens to take at any given moment.
Educating people not to rape is great. It does, however, only have an effect on a specific group: people who aren't intending to rape and just kinda derp their way into it via liquor, peer pressure, for some reason thinking what they're doing doesn't count, being idiots, whatever. As you put it earlier, "If someone wants to rape a person then they will do it." I don't know why you seem to think telling that person, "No, you shouldn't do that - rape is wrong," is going to change his or her mind. See, me? I'm 99% sure they fucking know that already.
The problem is they don't give a shit, so hey, maybe we should think of ways to try avoiding them. Startling insight, I know.
