We know that most people's intentions are good. We don't question their motives; we've never said they're unpatriotic, although they say some pretty ugly things about us. And we believe very strongly on preserving the right to differ in this country, and the right to dissent; and if I have done a good job of anything since I've been president, it's to ensure that there are plenty of dissenters.
