Where do the Conservative Christian Ukraine-supporting Freepers stand on this?
Well, the Ukrainian Orthodox Church of the Moscow Patriarchate is subservient to the Russian Orthodox Church. The Russian Orthodox Church fully supports the Russian aggression against Ukraine. If the leaders of the Ukrainian Orthodox Church of the Moscow Patriarchate condemmed the Russian aggression and risked being removed from their positions, I would agree that their church should be left alone. However, they more or less collaborate with the enemy.
The (Russian) Orthodox Church in America, on the other hand, opposes the Russian attack on Ukraine.
