What is it with dems and the use of thier finger.
Short answer?
If they have to emphasize their words with gestures, it means they are really lying their asses off (more so than normal)!
Plus, I think there is an unconscious desire to tweak those judgemental conservatives (and other non-libiots) with some judgemental finger-pointing.
Remember, a libiot is essentially a souless creature without any form of conscious or moral compass as it is understood my us normal folks, so they cannot experience any cognitive dissonance from any action committed by themselves or their kind.
