Washington ? Former Alaska Gov. Sarah Palin, defending herself against criticism following the Tucson, Ariz., shootings, said Monday that she used the term “blood libel” to describe comments made by those who falsely tried to link conservatives to the assassination attempt against Rep. Gabrielle Giffords.

Speaking out for the first time since she used the term in a video, Palin said on Fox’s Sean Hannity show that the term referred to those “falsely accused of having blood on their hands.”

Some Jewish groups strongly protested her use of the term, which historically was used to accuse Jews of using blood of Christians in religious rituals.

“I think the critics again were using anything that they could gather out of that statement,” she said. “You can spin up anything out of anybody’s statements that are released and use them against the person who is making the statement.”

Palin, a potential Republican presidential candidate in 2012, said the criticism won’t stop her from speaking out and accusing Democrats of taking the country in the wrong direction.

“They can’t make us sit down and shut up,” she said.

Palin said her political action committee’s use of crosshairs to identify targeted congressional districts for Republican pickups was not original and has been used by Democrats. As she spoke, a Democratic map was shown on the screen with circular targets of districts Democrats wanted to win.

The former governor said the crosshairs graphic was taken down by the PAC’s hired graphic artist after the criticism began. “I don’t think that was inappropriate,” she said.

The shooting on Jan. 8 killed six and wounded 13, including Giffords. Her district was among those in the Palin site’s crosshairs.

Palin insisted that she has “repeated over and over my condemnation of violence.” She said she was frustrated that conservatives who responded to false accusations –blaming them for the shootings — have become part of the story.

Asked why she was singled out for criticism, Palin, speaking from her hometown of Wasilla, said, “I know that a lot of those on the left hate my message and they will do all they can to stop me because they don’t like the message.”

Palin added, “I receive a lot of death threats. My children do.”
