In trying to avoid accountability for, among other things, placing gunsight crosshairs on a political map including the district of wounded congresswoman Gifford, Sarah Palin tells us, using a standard rightwing fallacy, we should place 100% of the blame on the shooter and "restore accountability in America." That way, the blame is taken off herself. Palin's "logic": We need to restore accountability in America, therefore I'm not accountable.
Obviously a democracy can't function with this level of illiteracy actually in play amongst its citizenry.
The standard Libertarian/rightwing conservative fallacy (normally used to rationalize welfare for the rich and absolve them of responsibility--see below) that everyone lives in a vacuum, there's no interdependence, no interaction, and no one and no thing ever influences anything or anyone else ("personal responsibility" is the phrase conservatives developed to fool people) is what Palin falls back on here, while going on TV in an attempt to--you got it--influence others.
"Personal responsibility" is a logical contradiction. All responsibility is social, therefore "personal responsibility" equates to, logically, irresponsibility. The syllogism: Everyone's responsible for themselves, therefore, I'm not responsible. (Works well for the idle investor class cashing in via free market economics on the backs of working people, for example.)
What's wrong with the concept of responsibility? Nothing--it needs no modification. "Personal responsibility" therefore actually equates to irresponsibility, and the phrase is used for the purpose of abdicating actual responsibility.
