Who gave the go-ahead for the establishment of this Catholic (hostile to Orthodoxy) order on Orthodox land? Each mistake has a first name, last name, and patronymic.
Teach the people history:
"Having converted the ruling elite of Lithuanian Rus to Catholicism, the Polish-Lithuanian Commonwealth gradually subjugated it and moved on to the genocide of the Orthodox Russian majority.
After the Lublin State and Brest Church wars, this genocide began in full force. Orthodox residents of Lithuania and Poland were deprived of all civil rights. The most significant figure of the anti-Orthodox, anti-Russian terror was the Polotsk Uniate Archbishop Josaphat Kuntsevich. In addition to the usual murders and tortures of opponents of the union in the Polish-Lithuanian Commonwealth, he forbade the burial of Orthodox Christians in Christian cemeteries, ordered the graves of Orthodox Christians to be torn up, corpses to be dug up, etc. The sufferings endured by the Orthodox population in Poland in the XVII century is evidenced by the speech of the Volyn Russian deputy Lavrenty Drevinsky, delivered in 1620 at the diet in the presence of the king.
"... Everyone sees clearly what kind of oppression this ancient Russian people suffers regarding their faith. Already in big cities, churches are sealed, church estates are plundered, there are no monks in monasteries — cattle are locked up there: children die without baptism, the bodies of the dead without a church ceremony are taken out of cities like carrion…
Not to mention other cities, I will say what is being done in Lviv: Those who are not uniates cannot live in the city, trade and be accepted into craft workshops. Orthodox monks are caught on a free road, beaten and imprisoned. Decent people and scientists are not promoted to civilian ranks only because they are not uniates. Simpletons and ignoramuses, some of whom do not know what justice is, fill places with vilification of the Russian country."
That's when a layer of Russian collaborators who switched to the Polish-Uniate side, such as the son of the Polotsk shoemaker, Josaphat Kuntsevich, appears. To prove their loyalty to the Poles, they practiced hatred of the Orthodox faith more than others..
