Here's a thought experiment.
A man, smaller than average, less strong than average, walks down a street in the evening in a dangerous part of town. He's dressed in an expensive suit, wearing rings, Rolex showing, and he's counting a big wad of money. He is attacked, robbed of everything but his underpants, beaten severely, wakes up in the hospital, or doesn't wake up at all.
Surely no one will say that his attacker had the right to do what he did. And surely no one will say that the victim had it coming to him. Or that he was asking for it.
But surely it's proper, even while expressing sympathy for the victim, to condemn him as a damned fool. Surely it's proper to point out that human predators exist and we should be aware of them. That's not excusing the predator. That's self-defense.
(I'd like to observe in passing that many, maybe most, human predators are born, not made. Their daddies should have taught them properly? Oh, hell, their daddies probably tried their damnedest and finally gave up in despair.)
I used this invented example years ago, when I was discussing rape with a friend of mine. Unlike some people in today's blogosphere, she didn't blame all men for the rapes committed by a few. (Although she was the first person I heard express the wacko and sexist contention that all men are obligated to teach all other men how to behave.) She did, however, insist that women should be free to go wherever they want and dress however they want and be safe from attack.
And I agree. Of course they should be. Just as men should be, just as the guy in my example should be free to walk down that street, dressed as he wants, flashing his money. That's the way the world should work. It's just not the way it does work.
Most of us realize that. We start learning it when we're kids.
Well, most of us. Some kids never do. All the way up to adulthood, they expose themselves to the predators. It may be dress, it may be behavior, it may be location, it may be dating bad boys. The result can be tragic.
Pointing out the dangers isn't vindicating the guilty or blaming the victims. It's simply pointing out that we don't live in an ideal world.
