First of all, regardless of who did what subsequently, the Torah DID outlaw intermarriage, long before Ezra in Devarim/Deuteronomy 7:3. The fact that Shicken doesn't mention this reveals either his complete ignorance, or intellectual dishonesty. The examples that he gives for Biblical characters who married non-Jews reveals the same level of ignorance/intellectual dishonesty. For example, Ruth clearly converts to Judaism when she states that she pledges loyalty to the Jewish nation and G-d. Uriah "The Hittite" - even if you subscribe to the interpretation that he was, indeed a Hittite and not an Israelite who lived in Hittite territory (such terminology is often used in the Bible), of course it was a sin for David to do what he did, if for no other reason (and there were many) than the fact that Uriah did nothing wrong in marrying an Israelite woman - the prohibition is on the Jew/Israelite, not the Gentile. And without going into further detail, for a champion of secularism it is amazing how far Shocken idolises Biblical characters such as Solomon and even Ahab, clearly implying that they couldn't possibly have acted wrongly. I suppose that the secularists and Chareidim have something in common there...
