I don't really see those as being opposite. It seems like Podkarpatska is saying that to force a Roman Catholic who wants to be a different kind of Catholic to obtain permission from his Latin overseers to do so doesn't make them seem very equal. What I am saying is something different, namely that if you are Catholic and all rites are equal, why do you need to "switch" in the first place to be a part of another church? I could go to live in Armenia for some reason, and I would be under the bishop of wherever it is I reside. It would not make a difference that I'm Coptic Orthodox and not Armenian. (This is how it SHOULD be, anyway, but of course in places like Lebanon, the Copts established a church despite there already being Armenian churches in the area...I don't know if there were transportation issues or what.)
Rather, what I have seen (admittedly on the internet, as I'm not longer interacting with people in Catholic churches in real life) of this phenomenon as concerns transfers from one Catholic Church to another is a lot of disaffected Latins deciding they would rather be Byzantines, and hence changing churches/rites/whatever because of their personal disgust for the Latin rite or their personal love of the Byzantine rite. That's what I meant to address in my post. We don't become members of other churches just because we decide we don't like the one we're in. When I first moved here to NM, we had Ethiopians worshiping with us in the Coptic Church, and apparently before I was here we had Armenians, as well. If you want to be OO here (or already are), you worship in the Coptic church that's already here. Of course, many larger places have many different kinds of churches that people can go to, but from what I've been told this is not preferable (it's understandable, it's reality, but it's not preferable), as it tends to create a situation in which the Ethiopians stick together, and the Copts stick together, and the _____ stick together, and as a result are isolated from each other along ethnic/cultural lines (taken to its extreme, this can become phyletism, wherein people not of X background are not welcome in a particular church).
