Lies: And the Lying Liars Who Tell Them (2003)
Context: If you listen to a lot of conservatives, they'll tell you that the difference between them and us is that conservatives love America and liberals hate America.... They don't get it. We love America just as much as they do. But in a different way. You see, they love America like a 4-year-old loves his mommy. Liberals love America like grown-ups. To a 4-year-old, everything Mommy does is wonderful and anyone who criticizes Mommy is bad. Grown-up love means actually understanding what you love, taking the good with the bad and helping your loved one grow. Love takes attention and work and is the best thing in the world.
That's why we liberals want America to do the right thing. We know America is the hope of the world, and we love it and want it to do well.

Variant: and it ought to make us feel ashamed when we talk like we know what we're talking about when we talk about love.
