Well, since the scope of this thread has grown far beyond what I envisioned...
First, please note that I have never stated here, or anywhere, that I was asking for re-baptism, but for baptism. That ought to tell you all you need to know about my views on the matter.
Second, as far as there being no substantial differences between Orthodoxy and Catholicism: please read Orthodoxy: Courage to be Different, Strength to Remain the Same by Fr. Mateja Matejic and see if you can honestly hold on to that opinion. Or you can read anything by St. Justin Popovich. I have deliberately not rocked the boat here or elsewhere, but I can honestly say I've had to re-learn Christianity as an Orthodox catechumen. Before I left for Orthodoxy, I had a mild argument with my Eastern Catholic pastor. He tried to hook me with the "does it really matter if you stay Catholic or become Orthodox- they're really the same". I sank his battleship right there, saying, "The truth is out there. You and I may disagree about where the truth is. Catholicism and Orthodoxy are very different, and they can't both be the true Church. Disagree, yes - interchangeability, no."
OK, now I've vented my spleen. Oh, and by the way, I have found no moral waffling at my parish.
You vented nicely 
I would be happy to read the book. Where can I find it?
Peace,
Polycarp
