Palin responded, "There is always going to be an element of those who want to be part of a movement who have their own ideas of where the country should go or what's going on with the country."
O'Reilly interjected, "What do you do with these people?"
"You don't take away their First Amendment rights and say, 'You cannot speak about those things or ask those questions you want answers to.' That's part of democracy at work."
Palin, who said she does not believe in the birther claims, suggested she is not overly concerned about the birthers hampering the Tea Party movement: "I see the danger of more of the same of the mainstream media wanting to paint Tea Partiers as radical, wacko conspiracy theorists."
During her appearance on the Fox News show, Palin also criticized the Fox show "Family Guy" for its recent reference to her son, Trig, who has Down syndrome. In this past weekend's episode of "Family Guy," a character is dating a girl with Down syndrome who says, "My mom's the former governor of Alaska."
Palin said, "When is enough enough?"
