You make some very good points there, but I think one needs to be added: I don’t think you have sufficient appreciation for the variety among Eastern Catholics. Let me just mention two dimensions.
First, only 14 are Greek-Catholic Churches. The 8 Oriental Catholic Churches are another story entirely. (And some might even object to that statement as simplistic and misleading, saying that the term “Oriental Catholic” is just a catch-all for Catholic Churches that are neither LC nor GC.)
Secondly, the Union of Brest and the Union of Uzhgorod were specific local events, but many people speak (on blogs and forums at least) as though they were the norm everywhere. More to the point, when you get away from the particular lands where those unions took place, you find Greek Catholic churches (in the Balkans for instance) that are pretty much like the Western-Rite Orthodox (in reverse).
I thought seriously about doing something like that, probably three or four different times over the last few years, back when I was spending 10, 15, or however many hours per week here. (Eventually other circumstances in my life changed; then it didn’t take much will power to limit my forum-time, since I simply didn’t
have the time.
