Wayne LaPierre, the executive director of the National Rifle Association, angrily accused President Obama on Tuesday of demonizing law-abiding gun owners and of wanting to put “every private personal firearms transaction right under the thumb of the federal government.”

In a fiery speech at a hunting conference in Nevada, Mr. LaPierre criticized Mr. Obama’s Inaugural Address on Monday when the president said Americans should not “mistake absolutism for principle.”

That reference, Mr. LaPierre said, was intended as an attack on the N.R.A. and gun owners who believe that the Second Amendment to the Constitution provides an absolute right to bear arms.

“I urge our president to use caution when attacking clearly defined absolutes in favor of his principles,” Mr. LaPierre said. “When absolutes are abandoned for principles, the U.S. Constitution becomes a blank slate for anyone’s graffiti.”
