If the thought of your donation to People for the Ethical Treatment of Animals (PETA) winding up in the pocket of a domestic terrorist isn’t enough to make you think twice about writing another check, maybe this news will.

Charity Navigator, the nation’s largest nonpartisan evaluator of non-profit organizations, announced yesterday that PETA received a “one-star” rating (out of four) in the latest edition of its nationwide service. This “Poor” showing means that Charity Navigator has determined that PETA “Fails to meet industry standards and performs well below most charities in its cause.”

You can’t do worse than one star, right? Don’t be so sure. PETA’s “Foundation to Support Animal Protection” — now doing business as “The PETA Foundation” — was one of just 23 organizations nationwide to receive zero stars (“Exceptionally Poor”).

Other activist groups in the one-star group include the Humane Society of the United States, the National Humane Education Society, Humane Society International, and The Greenpeace Fund.
