In my original post, I agreed that such practical strategic alliances were a good thing. I of course believe that any talk of intercommunion is extremely premature.
My real point was that Metr. Hilarion shouldn't overestimate the level of practical support such ideas would get within a largely liberal Catholic laity and clergy, at least in America.
And of course, as has been pointed out, we Orthodox are not without our problem children ourselves (Dukakis, etc...), although I think that our laity and clergy as a whole in America are far more traditional than are the Catholic laity and clergy.
Tih'on of San Fransico comes to mind...
