First off, the comparison between rapists and lions is ridiculous. When we're discussing rape and rape culture, we're not talking about animals attacking people. We're talking about people attacking people.
But, for the sake of argument, I'll play along with this particular scenario.
Let's say that I do live in the savana, as many people do, and that there are lions. And let's say I wear a suit made of meat (maybe Lady Gaga is making a visit and it's an hommage of sorts). If a lion attacks me, I could potentially take off the meat suit and toss it at the lion to stave off attack, since the lion will be after the meatsuit, and not necessarily me.
Heck, if I left the meatsuit out on the line, the lion would go after it. If the lion/ rapist analogy were accurate, then I could leave skivvies or miniskirts or any other manner of "slutty" items on the fence around my house to deflect the rapists. Or, I could keep some lingerie in my purse, and if I were feeling threatened, I could toss those at the potential rapist to distract hir long enough to get away.
Or, let's say I don't wear a meat suit. Well, to a lion, I am a meat suit. So, unless I'm wearing a bearproof (or lionproof) suit, then I'm still vulnerable.
Now, taking from the above example, let's say that my family and friends didn't let me know that I'm still meat to the lion even when I'm not wearing the dreaded meat suit. Let's say they also didn't tell me that lions can be my friends and family members and coworkers and spouses. Let's say that they think the lions only live in the savana and attack meat suits, and then blame me when I'm attacked in my home when wearing a night gown. How did this meat suit "advice" protect me?
Also, if we were talking about actual lions, it would be pretty easy to eradicate them. Humans have been driving other species into exctinction for at least hundreds of years, now. If I could just shoot and kill these lions without censure or recourse or being more heavily punished than the lion that attacked me, then this would be an entirely different situation.
As it stands, I'd much rather try my chances with a lion. At least I can spot a lion, I know what a lion is, what to expect from a lion, and if I were to get mauled by a lion no one would debate whether I got mauled or was just faking it.
But, seriously, tigers are fucking scary.
