The IRS is not enforcing a corrupt law, and the story Fox News doesn't want you to know about the IRS' conservative "charity" crackdown is that all of those charities were openly violating tax laws to the private inurement of their executives and challenging the IRS to do something about it, knowing that they had members of the House GOP in their pocket to prevent IRS action.
I wasn't speaking about that case. I was talking about how the tax law is currently written to favor some groups at the expense of other groups. And to be honest, this doesn't even have to be true. Only the appearance of it has to be seen by enough of the population for the reaction I describe to happen. Even if you think the tax law is completely fair, you would have to admit that significant portions of the population are not in agreement, and their views of the IRS will be driven by their views of the tax law.
