"Take a real scandal (NSA) and link it to a fake one (IRS)"
Translation: "Take government malfeasance that I imagine affects me personally and link it government malfeasance that I don't think impacts me personally...yet"
You (and so many others) fail to appreciate what's obvious to others of us: that while the NSA behavior is egregious, it's now out in the open, and you can take steps to protect yourself. And if you already assume the worst--that the NSA is scanning/saving *everything*, then that can't get any worse.
But the extent of the IRS behavior *isn't* out in the open. It *can* get much worse. If there's *any* politically motivated behavior going on the the IRS, then that is tacit approval and groundwork for more. And you won't think it's a "fake" scandal in a decade when, left unchecked, you find yourself the subject of a tax audit because you donated to the political party not in power. They can put a lien on your house. They can garnish your wages. In terms of practically achievable damage to the average citizen's life, the IRS is far more dangerous. The power to tax is the power to destroy.
You can stymie the NSA. You can't stymie the IRS.
