I generally agree with you and enjoyed your personnel account of moving to the "political dark side". I would argue, however, that the darkest of political sides is center. We argue against both based on core believes/values and are completely accepted by neither. If we had a robust middle ground, those at the fringes of the Right and the Left would be grossly outnumbered... all it takes is a vote for Independent!
Well... all it really takes is an Independent candidate that doesn't put their foot in their mouth during the run up for an election... but my point still stands.
Upvote for you, by the way.
