You’re not Orthodox, you’re a neocon, and you support the Deep State coup (Nuland, McCain, etc.) in Ukraine which has even brought Ukrainian Nazis to power.
So your scenario is worthless! This is no Brexit!!!!
We have Ukrainian American fellow believers in our OCA parish. If OCA is also forced to break communion with the Ecumenical Patriarchate, I expect NONE of them to leave!!!! And I also expect my Serbian parish to take the side of most of world Orthodoxy against the EP as well.
There are moves afoot to limit the damage. I hope that they succeed. Lord have mercy!!!!
Meanwhile:
You may speak for Serbia, but you do not speak for Moldova, Montenegro, or Macedonia. They want their own churches.
Even Belarus may follow Ukraine’s footsteps at this point.
