First, is Rome "behind" the tactics you talk about?
And secondly, I ask you again, WHY would a Polish Catholic try to convert an Italian Catholic? Your comparison of Ukranian Orthodox and Ukranian Catholics are different comparisons.
Regards
1. Would a Polish Catholic try to Convert an Italian one? NO! Then Why would Catholics, in communion with Rome, who is in one ear telling the Orthodox patriarch that we are all part of one true church be converting Orthodox parishioners, and challanging orthodox properties?
2. If Rome isn't behind it why not put a stop to it? Rome recently had a chance when the Uniate church wanted to move it's main administration to Kiev, a central Orthodox city, from Lviv. Rome refused to intervene.
