Twenty-eight groups representing millions of hunters and sportsmen are demanding that the conservative radio commentator end his collaboration with the [Humane Society of the United States] and stop “helping them to mainstream their image in the minds of reasonable people.”

“Despite a few programs designed to attract support from the general public, HSUS is in fact an organization that opposes hunting, fishing, and trapping,” the groups, including Ducks Unlimited and the U.S. Sportsmen’s Alliance, wrote in a letter last week to Mr. Limbaugh…

The Humane Society’s president and chief executive, Wayne Pacelle, said the issue shouldn’t be political.

“I’m embarrassed for them that they would criticize Rush for amplifying our message that dogfighting and other malicious forms of animal cruelty are unacceptable in society,” he said.
