"The Physicians Committee...is a fanatical animal rights group that seeks to remove eggs, milk, and meat from the American diet, and to eliminate the use of animals in scientific research. Despite its close ties to violent animal-rights zealots and “above ground” animal activist groups like People for the Ethical Treatment of Animals (PETA), PCRM has successfully duped the media and much of the general public into believing that it represents the medical community.
While PCRM presents itself as a doctor-supported, unbiased source of health guidance, the group’s own literature shows that 95 percent of its members never graduated from medical school. And the American Medical Association (AMA), which actually represents the medical profession, calls PCRM a “fringe organization” that uses “unethical tactics” and is “interested in perverting medical science.”
