Literally everything Putin does is quite the opposite of Christian ethics. So their use of religion is 100% instrumental, that’s obvious.
But then my thinking goes it’s the country where people are being literally jailed for 7 years for merely saying things like “Russia invaded Ukraine” and that’s enforced with full severity. And then you’ve got a celebrity priest (Kirill) or celebrity journalist (Solovyoev) ranting publicly about migrants or anyone else… and nothing happens.
My logic is therefore that this must be intended. Their ranting is a performance that serves a specific purpose. This could be just offloading popular sentiments, but when so closely correlated with Putin’s “multiethnic” talk I believe this is too close to be a coincidence and these two messages are intended to play together.
Practical verification of my hypothesis: when I’m talking to people I know in Russia, especially in Caucasus (multiethnic region) I hear the argument “if not Putin we will start killing each other” so frequently it almost became a cliche.
