It's blatant that she's using crosshairs and "reload" as a metaphor for people to regroup and continue to fight health care reform. I am completely flabbergasted that someone with such a level head on her shoulders (ie, you) would take it literally. I would have thought that only people who are already over the brink would think "Oh, Sarah is telling me to go get an actual gun and actually shoot these people."I'm completely serious, and I don't see how you could take it metaphorically. Now, I did say that she's probably not serious, but it's pretty damn blatant.
She is serious about regrouping and fighting health care reform. She wasn't ever joking about actually shooting people.
