Reality TV star Sarah Palin has been getting a lot of heat from animal rights activists after shooting a caribou on her TLC show, "Sarah Palin's Alaska," -- and the former Governor had some words for them Friday morning in an interview with "Good Morning America's" Robin Roberts.

"We eat, therefore we hunt -- and I am thankful that I get to feed my kids organic food," Palin said. "If they don't wear leather shoes and a belt and drive a car with leather seats and they eat no meat, then they have somethin' to say. And I can listen to them when they say, 'How dare you kill an animal to feed a family?' because they don't participate in that. And at least they're sincere about it."

Palin was appalled by a comment made last week by Hollywood writer Aaron Sorkin, saying she was a "phony pioneer girl" who killed an innocent animal for political gain, and she addressed the comment with Robin. "I'd say 99% of the critics, you know, they're wearin' their leather belts and they're eatin' their hamburgers somewhere -- and they're gonna tell me that it's immoral or not the right thing to do to go out there and actually harvest that resource, that piece of protein myself?"
