I have to confess, to me the complaints about Uniatism sound an awful lot like an army going into a battle and then saying "Oh no! They're shooting at us!"
Of course they are. You don't have to like it, you don't have to think they're in the right, but as long as the Roman Catholic Church believes she is the One True Church, this is what she will do. Does not the Orthodox Church accept converts from the Roman Catholic Church? Does she not have a Western Rite?
Although some of the tactics historically used by Uniate hierarchs and those associated with them were despicable, the mere existence of the Unia seems to me no more something to be upset about than the fact that the enemy shoots back in the aforementioned battle.
