"Jew can become Russian with easy but he should completely forfeit his Judaism.
Why is that? Because you say "Jew can become Russian with easy but he should completely forfeit his Judaism.
The form of Christianity that I'm acquainted with, precludes one from giving allegiance to any over and above God himself, just as it was so for the prophet Daniel, Shadrach, Mesach, and Abednego [whether or not i can spell their names properly right now].
As such, as far as I can judge, both a proper Christian, and a "proper" Jew, must continue in this example...resisting authority only when it opposes God. Since this type of thing is important, not to be taken lightly, then both Christian and Jew needs to actually get to know this God, in a personal way, beyond just knowing "about" Him -- though for some, faith alone, based mainly on simply knowing about,(far short of "knowing", or having experienced His presence, His Spirit, heard His voice, or other contact with Him directly) has been enough for them to serve God, over serving temporary rulers, who are merely men.
Whichever way one gets there, serving God foremost is the most "patriotic" thing a person could ever do, regardless of what Nation one lives in, for He is no respector of persons, or Nations, either. Though many Jews do not accept it, Jesus said to them, "do not say 'we have Abraham as our Father'", as justification...
He knows who their father, and mothers are, and they should too. It's in their book! [old testament scholars will know what i'm talking about, heheheh]

Russian Ortodox Church is called Russian not by coincendence. She prays on Russian language. Her cannonized saints are Russian historical figures and much more. Russian ortodox beliver are teached by Church how to be Russian and cristian.
Russian Ortodox believer has to ally himself to Russianry and Russian state.
That is why the Bolshevicks when took power attacked Church in first since they perfectly knew that Church is thier moral ideological enemy. Notice Bolshevicks didn't attack with such force neither Mosks nor Synagogues since they weren't such danger for them.
Hence I cann't imagine how the follower of other faith may become real Russian.
