On Tuesday big-game hunter and Minnesota dentist Walter Palmer ignited an international firestorm after news reports revealed that he and his guides may have lured a lion named “Cecil” out of his protected sanctuary in Zimbabwe’s Hwange National Park. If these allegations turn out to be true, and Dr. Palmer knowingly hunted the lion illegally, of course he should be held fully accountable.

Regardless of your feelings about big-game hunting, we should all be glad that PETA doesn’t define what “accountable” is. The group tweeted that Palmer should be “extradited, charged, and preferably hanged.” (Emphasis ours.)

But apparently PETA doesn’t think that killing other cats warrants a hanging. Every year, PETA kills the vast majority of cats, dogs, and other domesticated animals that come into its shelter. Killing at the rate of about 2,000 per year, PETA has killed more than 33,000 animals since 1998. PETA has even advocated for the mass-killing of outdoor cats under the preposterous theory that these animals are better off dead.

So when we hear PETA call for the death of a man who may have illegally killed one animal, it’s important to keep in mind the organization’s own record and advocacy.

Frighteningly, PETA does not just promote violent rhetoric.

As we reported in May, the FBI’s Domestic Terrorism Operation Unit reported that PETA provided “at least tacit support for the [Animal Liberation Front] and its illegal activity.” The report also noted PETA gave $70,000 to the defense of a convicted arsonist, in addition to providing funding for the defense of other dangerous criminals. And PETA also gave money to the violent Earth Liberation Front.

Others have adopted PETA’s style of violent speech; Piers Morgan advocated that we maim Walter Palmer so we could “calmly walk over, skin him alive, [and] cut his head from his neck” These sorts of threats have now spread to the dentist’s Yelp page.

It’d be nice if these holier-than-thou activists actually were “humane” to people.
