My point about the Latin Church in Lviv is that Eastern Catholics cohabiting the same area as the Latins means absolutely nothing when it comes to celibacy.
The Ukrainian Church kept its married clergy after union with Rome despite the fact it was in Poland, which was part of the Roman patriarchate as you put it.
I might also note that Pope Benedict XVI suppressed the patriarchate after he became Pope.
I hope someone told this guy:

(IOW: No he didn’t.)
And you’re still completely missing my point: The Ukranian Greek Catholic church was an historically established church in the Ukraine, but there were also many Polish Latins who had remained in union when the UGC was in schism. There’s no such situation here in America with the Melchites. The Melchites never had Americans priests who were married, and their presence in the US was established long after the Latins.
That said, if they can work it out some way to have married priests without encouraging men to switch rites to become priests, let them go for it!
