I don't pay attention to any religious leaders, mostly, and this is the first sight I've had of this comment.
I read (in isolation) that comment as being aligned to you, i.e. the faux-nationalists are the more despicable, though if the natively-nationalist actual Russians are being 'significantly excused' in surrounding text (that you don't include) then I can clearly see the rift between you and His Popeness. Being one of the misguided mass, in any culture but especially one which industrialises the misinformation machine, is a clear mitigating factor - albeit only marginally/comparatively so.
For a religion where "hate the sin, love the sinner" is the order of the day (theoretically!), I could certainly see the Pope not going for full national condemnation, but making even an equivocal-looking wording into what is actually a fairly serious escalation of opinion. (Not that the ~0.1% of barely-countable Catholics, within Russia, can do much to sway things in response.)
But I generalise. I don't know much at all about the Buryati. And Chechnya is famous to me mostly for an earlier clusterfuck of opposing ideologies (and I couldn't even say for sure which was objectively the least horrible) that seemed never ending (did it ever end?) and definitely created motivated radicals, some of whom are probably very useful enemies to deploy into your own most recent theatre of conflict. Useful idiots, at best; combat-hedonists, more likely. Very deliberately used as such by the Kremlin, naturally.
Not at all to dismiss your heartfelt report of your feelings, punctuated by your various blackouts. I sincerely hope to see a lot more from you and, though my words alone may be insignificant help, I'm trying to radiate only the best of best wishes to you and the others in your situation. Please continue to take care/stay lucky. (And the same to 'woke' Russians out there. Not so much potentially at the wrong end of a missile, I know, but still uneasily having to navigate a hostile political environment/etc.)
