Dennis has never been a strong opponent of divorce. I don't know where this idea comes from but certainly not from listening to his radio show.
What is relativistic about him? What makes him a hypocrite? Especially since he is not a strong critic of divorce?
An orthodox, or even just a plain "religious" Jew, would not be a "mild" critic of divorce. Family, responsibility, constraints on behavior, absolute values are all part of the religious person's life. He's now off the plantation twice in 17 years, and something seems fishy to me.
He apparently is merely a cafeteria Torah follower, picking and choosing among the offerings, and so how can he deride other lifestyle "choices " like polygamy, homosexuality, and so on, without sounding like a hypocrite? And without theologistic support, what has he to offer? He's not a tax adviser, he's a proffessional moralist. And he's full of crap, as far as I can tell.
