So I hardly know where to begin here. How about this: humans have spent quite literally thousands of years trying to rid the world of the things that kill us. In Europe, wolves were the predator that did the job of killing humans best. You don't get to be the star of essentially all of a culture's fairy tales if you aren't the thing of nightmares. They are, quite literally, monsters.
From the LA Times article:
Environmentalists argue that grazing practices are part of the problem and the wolf reintroduction program has failed because of mismanagement by the federal government.
Here's why the program has failed: they're wolves. They eat stuff that we don't want them to, like cows and small human beings. Ranchers are going out of business because, surprising to no one but "Bud Fazio, coordinator of the Mexican gray wolf reintroduction program", wolves are really good at killing cows. What?! Millions of years of selective pressure optimizing large predators made wolves good at what? Killing what? Yes, killing cows, you idiot.
"One thing about wolves is they bring out extreme emotions..."
Yes... fearing for one's livelihood tends to do that. I am pretty sympathetic to the idea of protecting endangered species. I'm soft-hearted about it, and I hate the idea that we kill entire species for non-critical activities. But I consider ranching pretty critical.
I want to protect wildlife, but we can't be stupid about this... wolves are enormously dangerous and we can't pretend they are not.
