Not sure this is true. Didn't find any such people online or elsewhere.
Being Z means mostly fully trust the state propaganda, and this prevents being pro-navalny.
I'm honestly amazed Putin hasn't just had this guy killed. He's killed so many other opposers to his regime.
Is he scared Navalny would become a martyr? Or is having him in prison like a trophy or something? >

If Navalny dies, his supporters will find a new leader of their cause, and become less manageable. As long as he lives, his supporters will never agree on a replacement. >

True, but there are Pro-Navalny Russians that have since gone full Z.
