Questioning patriotism

One of the left's biggest whines over the last 4 years has been about people questioning their patriotism. For some reason, the level and nature of their patriotism is supposed to be unassailable, even tangentially. I don't buy it. If I want to question someone's patriotism, I'll do so. And if I do, that person has some options: Ignore me, admit that they aren't patriotic or defend why they are. Notice that pretending to be patriotic isn't on that list. While anyone has the right to pretend to be patriotic when they really are not, I reserve the right to point that out when I see it.
