How refreshing that there are people like Kirsten Powers in the world.

In her new book, the outspoken, unapologetic liberal Democrat has taken aim at the militant search-and-destroy tactics employed by many liberals to shut down civil discourse and bully ideological opponents into submission.

Not surprisingly, many on the left have turned their attacks upon Ms. Powers and her book, proving her point by doing exactly what she accuses them of doing.

The intellectual laziness of groupthink lies at the heart of the deep divisions that are tearing this country apart.  If more people would listen — listen to each other, and listen to Ms. Powers’s message — America might start turning back toward a culture of problem-solving and away from character assassination and political dogma.
