A ‘blood libel’ is much more than just a ‘false accusation’, and there’s no way that the speech-writer couldn’t have known that.
The problem is not martial language. The problem is the discussion of martial solutions, mentioned as actual policy options. That’s what “eliminationist rhetoric” means, you weaseling fucks.
ADDENDUM: Sarah Palin fans the heated rhetoric flames by playing the victim card and describing criticism as a “blood libel”. Seriously.
