Mark Bibi is familiar of the tactics of those Leftists who will brook no opposition to their anti-human agenda.

Animal-rights fanatics have figured out that you beat medical research that uses animals not by going after the researchers, but by going after those who do business with the researchers. They cow Wall Street, not by flying into buildings, but by trashing members' clubs.

Bibi knows what it is like to be a target. Anonymous thugs vandalized his house, smashed his car's windshield and made nasty phone calls to his home in the middle of the night.

Skip Boruchin, the only trader who refused to be scared out of business with Life Sciences Research, testified about the relentless intimidation he and his family endured. Activists painted his yard red with slogans such as "Skip is a murderer." On line, they called him a "child pornographer." One Web site instructed people to send sex toys to his ninetysomething mother at an assisted-living home. Another Web site listed the names, phone and Social Security numbers of 19 neighbors, and threatened to publicize information about their credit cards or medical history.

Violence? Well, there were the two bombs set at Chiron's Emeryville offices in 2003. Agents believe the second bomb was timed to go off as first-responders arrived. The FBI also believes the violence is escalating.

And their actions are violent – not limited to harassment or property crimes. And what’s more, they are willing to publicly state – under oath before a Congressional committee – that they endorse homicidal violence as justified against their opponents.

Jerry Vlasak, a Southern California physician who is spokesman for the North American Animal Liberation Press Office, also testified Wednesday. Vlasak dismissed the intimidation of Boruchin and others as "getting a little spray paint on the wall."

Committee Chairman James Inhofe, R-Okla., questioned Vlasak about a statement Vlasak had made defending the assassination of medical researchers. Once again, Vlasak justified violence. For "people who are hurting animals and who will not stop when told to stop," he answered, one option would be murder, a "morally justifiable solution."

Imagine, if you can, the outrage that would exist if mainstream pro-life groups took such a position (they condemn violence) – or if opponents of homosexuality endorsed the killing of homosexuals “who will not stop when told to stop.” There would be loud outrage from the Left – but there is not a word of condemnation when it is their ideological allies engaged in such threats of violence against those involved in legal activities – medical and scientific research designed to improve human lives.

And it isn’t just medical researchers and their associates who get it. Consider this incident from Chicago.

A day after speaking out against the city's proposed ban on foie gras, chef Didier Durand arrived at his River North bistro Wednesday to an unwelcome sight: a shattered window splattered with a liquid resembling blood and busted-up flower boxes strewn on the sidewalk.

Police say Cyrano's Bistrot and Wine Bar at 546 N. Wells was vandalized between 11 p.m. Tuesday and 9:30 a.m. Wednesday.

Durand, who had spoken at a City Council committee meeting Tuesday about the proposed ban, suspects animal rights activists are behind the damage. The Health Committee voted in favor of the ban.

That’s right – not only do they want control of your diet, but they will do their best to punish those who dare to speak against their radical agenda.

The time has come to shut down the “animal rights” terrorists. The freedom of Americans -- and our lives and health – demand it.
