Now, I'm gonna go out on a limb and extrapolate here, while leaving it to others to do the definitive experiment: we learned that, of those sadistic people who went out of their way to kill a non-threatening animal, 90% were SUV drivers. My bet is that if you were to interview those people you'd also find that virtually all of them are Fox-listening wingnuts.
Which is not to say that SUV drivers are all a bunch of killers. Ninety-four percent of drivers, after all, did what sane people would do; ie, drove on by. And many SUV drivers are liberals, no doubt. But of the deliberate swervers of their SUVs to kill, well, who does that? Tree-hugging vegans?
