IMO there's a difference between issuing a general warning, even if based on a specific example, and telling a specific person after the fact what they should/shouldn't have done.
"19 year old Katie got blackout drunk at a frat party and several guys there pulled a train on her. Best to stay sober and keep your wits about you in situations like that, lest bad actors take advantage of you. There are a lot of really horrible people out there whom you simply can't trust not to do you harm."
vs
"Well, Katie, you shouldn't have had all those Jager bombs if you wanted to wake up will all your orifices still their original size."
The two are hugely different, but it seems people are wont to treat them as being equal. Any suggestion that a generic person take precautions against being harmed is treated as victim-blaming a specific person and absolving the bad-actor in their case.
Yes and no. I agree, of course, that there's nothing wrong with giving advice, but part of the problem is that it's so one-sided, and also that people jump so quickly to what the survivor did wrong in cases of sexual assault or exploitation.
In discussions about drunk drivers killing pedestrians, no one goes "perhaps those pedestrians should've worn reflectors, not been drunk or listened to music on their headphones, and made sure to cross the street at crosswalks". Especially if the drunk driver had run people down deliberately.
It is curious how we tell girls not to drink too much so as not to be abused, but we don't tell guys to drink responsibly so as not to end up doing something you'll regret once sober. To the contrary, you often see drunkenness used as an excuse by people taking advantage of others: "sorry, I was wasted and didn't know what I was doing".
I went to an afternoon class on sexual abuse once, and one of the two teaching the class said that when she taught teens about sexual assault, she used to tell them, slightly paraphrased, that "I know you're full of hormones, and that you get even more horny when drunk, and that it gets even worse if there are pretty girls around, but if you're at a party and you're uncontrollably lustful, take a hike into the woods, take care of your problem on your own, and come back when you're ready to be around people again". If more people had this attitude, it might make a difference in the end.
