Those who carried out that first Tea Party were not protesting against government, or even against taxation. They were agitating for democracy. They did not cry "No taxation!" but "No taxation without representation!" They stood for principle--representative government--not policy.
Those who are protesting now are not arguing for democracy. Indeed, they argue against the results of democracy. For these are the people who lost in 2008. Their complaint is not that they have been deprived of representative government, but that they are in the minority. They object not to a lack of freedom, but to the result of free choice. They are perfectly entitled to their anger and to protest, but they are not the true descendants of the patriots in Boston that winter night in 1773.
