The Diocese of Worcester has canceled a planned speech by Robert Spencer at an upcoming Catholic Men's Conference. Normally, I do not approve of cancelling speakers slated to address a Catholic audience. I find such efforts counter-productive at best and moralistically reductionist at worst. But, there is really no reason to have a speaker who is just hateful, and Mr. Spencer's characterizations of Islam are hateful, extremely so. He never should have been invited in the first place.
