The PCRM is not really respected in the medical and science communities.

One criticism here from Tufts Univ. points out that, "In fact, in their zeal to make their point, the site’s authors often blur the line between scientific fact and conjecture."

Another criticism can be found here from the National Council Against Health Fraud. Neither of those are as acerbic as the criticism from activistcash.com, which characterizes PCRM as a "fanatical animal rights group" with in which 95% of the members are NOT health care professionals. "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.'"
