My experience is that feeding the trolls never gets you anywhere.
Uri isn't your garden variety troll. He is the embodiment of a new variety of gnostic heretic who believes that special knowledge alone can achieve Salvation and can elevate each above his fellow man. He just hasn't put the pieces together enough to recognize it. I am doing him a favor by pointing it out.
Nor does stepping on a cockroach, but it's still is quite satisfying.
