I'll chime in here, since I'm the guy who - literally - wrote the book on these idiots.
To clear up a couple misconceptions:
- PeTA is not an environmental group. They've never done anything, never spent one penny to help protect or preserve any wild country or wildlife habitat. Never.
- PeTA is not a pet rescue group. They operate a "shelter" in Norfolk that has almost twice the euthenasia rate as the metro Norfolk shelters. With their budget, they could fund a no-kill shelter in every state. They don't fund any.
- PeTA is not a health advocacy group. They promote nitwittery like that put out by the Physician's Committee for Responsible Medicine, which is three lies for the price of one - less than 5% of their members are physicians, they aren't a committee, as they're policy is dictated wholly by found and PeTA mouthpiece Neal Barnard, and the aren't advocating medicine, but vegan philosophy masquerading as science. PCRM is funded heavily by PeTA.
What PeTA is is a massive fund-raising and political advocacy group. Their goals are to outlaw hunting, outlaw the raising of animals for food, fur or leather, outlaw the use of animals in research or medicine, and to outlaw the keeping of animals as pets. (Yes, really.) They're extremely well-funded, and astute enough to enlist a legion of empty-headed Hollywood nitwits to make their cause appeal to those whose capacity for analytical thought is somewhat less than that of a stuffed artichoke. Sadly, these days that's a significant portion of the younger generation.
What PeTA poses to mainstream America is a threat every bit as great as Sarah Brady, Chuckie Schumer, and Hillary Klinton, and for much the same reason. They are fundamentally anti-freedom. Hunting, eating, guns, you name it.
