Of course the Physicians Committee for Responsible Medicine is lashing out at McDonald’s for adding chicken to its salads (“Salads can supersize our waistlines,” June 4). What do you expect from an animal rights group?

That’s right. PCRM is not a legitimate medical charity. It’s a front group for People for the Ethical Treatment of Animals. PETA has already funneled over $850,000 of its tax-exempt money to PCRM. The two organizations share offices, staff and financial accounting as well. The animal rights watchdog newspaper Animal People News calls the two groups “a single fund-raising unit,” and accuses them of attempting to “evade public recognition of their relationship.”

These people and their “meat is evil” message are dangerous. But don’t take my word for it: The American Medical Association has called PCRM a “pseudo-physicians group” and considers its recommendations “irresponsible and potentially dangerous to the health and welfare of Americans.” PCRM has also been formally censured by the AMA.

Most Americans are too smart to take dietary advice from animal-rights zealots. But when activists put on the sheep’s clothing of the medical profession, it becomes harder and harder to know who’s credible.
