If I wanted to discredit the American Left, I might produce a piece of biting satire, like Why Mommy is a Democrat.
The punch line, of course, is that this is not a clever piece satirizing the Left but an attempt to promote the Democratic Party by satirizing the Right.
It looks like it really may be true that Republicans want the government to be your father, Democrats want the government to be your mother, and libertarians want to treat you as an adult.
