My suggestion: Learn to recognize a humor piece when you read one.
Though the author makes occasional attempts at humor to make digs at atheists, I would hardly call this a "humor piece."
He is obviously a proponent of one side of the issue; in fact, the article is rather polemic. By writing it, the author opens himself to rhetorical attack from holders of opposing views. I merely wished to provide a rebuttal to a few of his points.
As for your ad hominem: People who accuse others of lacking humor often lack it themselves.
