I have to wonder, don't the majority of Russians pretty much know that their government is full of shit?

Let me offer my perspective,as a Russian. People do not want to lose everything like they did in the 90s. Yes, everyone understands that the government is full of shit, but they believe in the belief (google it, an interesting concept) that it's virtuous to support a government.

It's like a classic trolley problem. Yes, you'd probably push that lever, but you know of consequences and you just purchased a car and your wife is pregnant. You are caught in this unending circle, you simply do not want to deal with it because it doesn't affect you. But when it does affect you, it's always the west: shock therapy of the 90s, current sanctions, debit card ban, visa bans, etc.
