She is 48 and has lived outside of Russia for 25 years
Formative years under a communist system and it's education system. If her Russian friends and family also have the communist "don't rock the boat" overhang it's easier to hold on to.
Can't understand it completely myself as I have always been a gobshite with a natural distrust of authority.
It isn't a perfect explanation though, and we have seen in America that smart folks living in a more open society completely taken in by Trump's bollocks.
People generally like the easy simpler narratives even if they don't always add up.
I've seen clips pop up on twitter of Ukrainians whipping people on their bare bottoms, I've assumed that they were punishing collaborators or saboteurs. And that's the explanation. Could be wrong, but I didn't want to spend time trying to corroborate or test this.
And there's limitations of doing that over their Internet and as someone with no journalistic training or experience.
Also saw a clip that claimed to show a Ukranian stabbing someone in a stairwell (no blood), I thought that looks staged. But I didn't bother to check it up.
Was I using critical thinking or the opposite because I chose to pick a narrative explanation and accept without bothering to test it?
In a complex and more interconnected world it is easier, and even essential to just switch off on subjects to help you get through the day. Maybe that's what your wife and other like-minded Russians are doing?
