I’m no Horowitz fan, but holy hell, I didn’t think the guy was this intellectually dishonest. Challenging someone to a written debate, editing their answers down, and then publishing the exchange with comments that you wish your opponent had participated more fully — when he did and you cut it! — is a rarely realized peak of argumentative weakness. I guess this is just one more of Horowitz’s never-ending contradictions — to reach this highest point of dishonesty he had to sink lower than we ever thought he could. Why Berube wastes his time on this guy I’ll never know.
