As some have already pointed out, even if men are told things like that it has no effect on the response to if they are robbed or assaulted. If a man walks down an alley wearing a suit made of clothing no one says "you were asking for it" or "well what did you think would happen". The theft is still prosecuted, and more importantly they aren't blamed for being mugged/robbed/whatever.
But they do. Not as loudly as the victim-blaming in rape cases but you do have examples of men being blamed for what happened to them by going to the wrong place at the wrong time, for "asking for it", for whatever other term you want to introduce. You do get men getting blamed for getting so drunk they couldn't think clearly and something bad happened to them. It simply makes less noise then when a victim is blamed in a sexual assault case.
The way victims get blamed in sexual assault cases is woeful enough to stand as an argument on its own. It doesn't need to be strengthened by making it relative and understating what it's relative to.
Think about the argument you're making. Would it make victim-blaming any better if it applied completely equally to men and women, to non-sexual assaults and theft the same way it does to sexual assaults and rape? Would it be an improvement if male victims of non-sexual assaults were blamed the same way for what happened to them?
Or is it actually a positive that in at least one area we don't blame the victim... or at least, not as loudly?
Most of what I have read on rape culture does not discourage people from saying walking down a dark street or whatever in general safety about life. It discourages that kind of "advice" in discussions of rape because it is so ridiculous and ineffective, etc.
I'll give a simple example.
British celebrity Joanna Lumley, as part of a wider interview said
She says: “Don’t look like trash, don’t get drunk, don’t be sick down your front, don’t break your heels and stagger about in the wrong clothes at midnight. This is bad. It’s not me being a snob about it. It's not me being an old woman talking to young women, its just standard practice for how our species should behave. Don’t behave badly.Cue hysteria
“I promise you it is better to look after yourself properly, which means behave properly, be polite, be on time, dress properly – I don’t mean dully – but don’t be sick in the gutter at midnight in a silly dress with no money to get a taxi home, because somebody will take advantage of you, either they’ll rape you, or they’ll knock you on the head or they’ll rob you.”
Let's look at what she was actually saying in context. She wasn't
giving advice on how to avoid being raped at all. She wasn't specifically talking about rape at all. She was bemoaning what she saw as "laddy" acts by women and she listed some possible consequences that could befall someone. I think her use of the phrase "will take advantage..." as opposed to "may take advantage..." but other then that is it terrible advice? Isn't it good advice... for all genders... in general?
Yet what do you think the comments focused on?
Do you think those that objected to her words on rape separated out the risk of getting robbed or non-sexually assaulted and sexual assault, mentioned why she was wrong to mention "silly" dresses but said that she had a point on the non-sexual offence?
Here's a clue... they didn't.
They threw out all of her advice as being part of the "rape culture" either by name or implication, said she was completely wrong and that she was issuing bad advise.
