"Progressivism, liberalism, or whatever you want to call it has become an ideology of power. So long as liberals hold it, principles don’t matter." -- Liberal Fascism: The Secret History of the American Left, From Mussolini to the Politics of Meaning
“We are fast approaching the stage of the ultimate inversion: the stage where the government is free to do anything it pleases, while the citizens may act only by permission; which is the stage of the darkest periods of human history, the stage of rule by brute force.” -- Ayn Rand
One of the most disturbing things about the IRS targeting Obama's political enemies for persecution is that many liberals seem to be perfectly fine with illegitimately using the power of government to hurt their political enemies. Certainly, no one in the IRS or in the upper echelons of the Obama Administration had a problem with doing exactly that since no one at the IRS was punished for targeting Tea Party groups until a big stink was raised publicly.
This is extremely disturbing because it shows a lack of respect for the Constitution, the rule of law and even for democracy itself.
When you start to conclude that it's okay for your side to ignore the law, break the rules and defeat your political enemies by any means necessary, you're veering into dangerous territory. It's dangerous because a republic can't function over the long haul when one side of the political debate is treated as above the law. Either the law applies equally to both sides of the political debate or good people will begin to feel that they have no choice other than to operate outside the law in order to get justice.
