While trying to avoid bitter partisan sniping is probably a good thing, I think the goal of avoiding politics is naive. Everyone is enmeshed in politics, like it or not. To deny politics is a form of political ideology itself. There seems to be a strong libertarian bias to this crowd, for instance. Libertarians seek to replace politics with markets, but that is in itself a political goal.

Another sad truth: even if we disavow responsibility for the actions of our political leaders, others will hold us responsible for them, given that we are a democracy and all. See here for some thoughts on how we are forced into group identification whether we like it or not.

Politics is not optional and if you are interested in overcoming bias I suggest that it's better to acknowledge that fact than bury it.
