purity quest

Once I concede that a non-political power wielder like myself or whoever I'm likely talking to has little or no impact on politics via voting or principled non-voting or internet blathering or activism intended to impact political decision-makers and the like, I'm left with symbolic tirades. Does it matter if someone voted for Obama or Romney? It's like shouting at someone for "hoping so-and-so gets hit by a bus." Your wishes have no effect on anything but damn, they're impure! Which would make the whole thing therapeutic. It was already that, but now the excuse is gone.
