Ingrid Newkirk is the co-founder (with Alex Pacheco) and president of PETA. She’s also a militant extremist who has been arrested more than 20 times, and an avowed supporter of the terrorist group Animal Liberation Front, saying, “I will be the last person to condemn ALF.”

Newkirk has supported the legal defense efforts of ALF criminals using PETA money (see Rod Coronado, below, who she has called a “fine young man and a school teacher”), has been subpoenaed in regard to her ALF connections, and has even been accused in court documents of participation in the ALF arson of a Michigan State University research lab. PETA has also donated $1,500 to the Earth Liberation Front, a “sister” terrorist group to the ALF.

A co-founder of PETA alongside Ingrid Newkirk, Pacheco also served as a spokesman for the Animal Liberation Front, a terrorist group according to the FBI, and has been subpoenaed in connection to ALF activities.

In college, Pacheco joined the Sea Shepherd Conservation Society, fleeing Portugal after his ship rammed another. A U.S. federal court has called the Sea Shepherds a pirate organization. Paceheco made his way to London, where he worked with ALF founder Ronnie Lee, before heading back to the U.S. and co-founding PETA.

A longtime animal rights activist, Coronado was sentenced in 1995 to 57 months in federal prison, for the 1992 arson of a Michigan State University research laboratory. He later confessed to at least six other arsons. While the FBI was most intensely investigating Coronado, PETA gave him over $70,000 in “grants.”

After serving time in prison, Coronado continued as an “unofficial spokesperson for the ALF,” and was arrested again in 2006 under anti-terrorism laws after he had described how to make an incendiary device during a public speech. He also served 8 months in jail for disrupting a government-sanctioned hunt.

Currently CEO of the Humane Society of the United States, Pacelle cut his teeth in the animal rights movement by violating hunter harassment laws. He even once wrote in an essay: “I don’t love animals or think they are cute.”

Slick enough to try to moderate his image, that hasn’t stopped the legal drama for Pacelle: HSUS was sued for bribery and fraud under the anti-mafia Racketeer Influenced and Corrupt Organizations (RICO) Act, settling for over $10 million in 2014. Pacelle had personally signed at least one check implicated in a scheme to pay a witness who lied under oath.

A former “Humane Education Lecturer” for PETA, Gary Yourofsky is also a convicted felon who served hard time. In his speeches, Yourofsky compares himself to Martin Luther King Jr., Gandhi, and Jesus. Yet, this king among men has been arrested over a dozen times for animal-rights crimes, and was sentenced in 1999 to six months in a Canadian maximum-security prison for a felony raid on a fur farm.

Yourofsky is currently with the vegan advocacy group ADAPTT, which he founded, and he claims to have given over 2,500 lectures in schools across the US and in Israel. He also openly admits on his website that he has been banned from five countries (the UK and Canada). The Jewish news site Haaretz notes of Yourofsky, “He is pleasant and polite, though he starts getting animated − arms flailing, pained expression − whenever he talks about the suffering of animals. But he does not deny the violent death he wishes to everyone involved in the fur, meat, dairy or poultry industries, and to anyone who eats or wears animal products.”

Jerry Vlasak is a medical doctor, but don’t let the white coat fool you: He has advocated for the murder of humans to push an animal rights agenda. Speaking at an animal rights conference, Vlasak remarked, “I don’t think you’d have to kill — assassinate — too many vivisectors, before you would see a marked decrease in the amount of vivisection going on. And I think for 5 lives, 10 lives, 15 human lives, we could save a million, 2 million, 10 million non-human lives.” The UK Home Secretary banned Vlasak from entering the country following his murder endorsement.

Vlasak is affiliated with the North American Animal Liberation Press Office (NAALPO) (along with Gary Yourofsky, who believes fur-wearing women deserve to be raped), which functions as a propaganda arm for animal rights terrorists at the Animal Liberation Front. Speaking to CBS’s 60 Minutes, Vlasak said that while he wouldn’t personally commit violence on behalf of animal rights, he is happy to “explain…why these people [terrorists] are doing what they’re doing.”
