When animal rights activists resort to phony letter-writing campaigns to promote meatless eating, they don’t deserve to be taken seriously. Lenny Dill’s Dec. 11 letter, “Heavy pollution caused by animal agriculture,” was a great example.

The exact same letter Dill submitted, word for word, also ran in at least 30 other U.S. newspapers this month. In each case, a different activist “signed” it. This is part of an organized campaign by the Farm Animal Reform Movement, a radical animal rights group that sends thousands of fake anti-meat letters to newspapers every year.

If you want to express a point of view in public, the least you can do is use your own words. But hundreds of animal-rights letters appearing on opinion pages this year were just carbon copies of each other. If animal rights groups want widespread exposure for their twisted message, they should buy advertisements like everyone else.
