Some of the issues Feldman brings up, including a LOT of the contradictions, are only problems for the American modern orthodox community, and are simply not issues for modern-orthodox living in Israel. 

Intermarriage almost never comes up in modern orthodox communities in Israel-- you'd have to work real hard here to find a non-Jew to marry.  And i've never seen a modern-orthodox or dati-leumi community here exclude a couple because one of them was less religious--as long as both were jewish.

There's no issue of conflicting loyalties, as modern orthodox are the most passionately committed to the state and to the army, even despite the Gaza evacuation. 

I'll bet a lot of money that Feldman, had he been living in Israel rather than America after high school, would never have dated nor married a non-Jew.
