Wow, Berube showed himself to be exactly what Horowitz describes - the prototypical leftist who when pressed with a well-supported intellectual argument responds instead with name calling, completely unable to muster an intellectual argument in support of his own position. A very skilful skewering of the left by Horowitz, with a disappointing but not unexpected performance by Berube.
Although the left may have some intelligence (the ability to remember the latest name calling response against the right), it has very little wisdom (the ability to constructively formulate new arguements).
No kidding. Berube embarrassed himself with that last reply.
