Russian mentality, as explained in those references, is something way beyond vodka, beyond orthodox faith, beyond soviet man, beyond many things. And possibility to adjust into new forms is that its made compatible with "russian mentality". But perhaps enough of this topic since it is kind of irrelevant, as it was meant only as reference to point out difference in influence of environment. How same things could not been enforced in... lets say France?
As example we could simply use Japanese noise, and japanese culture as reference too. How Japanese noise manifested itself very differently. Even in its vast diversity of sound.
I think bottom line appears, that you are worried of generalization & mistake what would misinterpret the individual. Lump him into group he doesn't feel being in. And I really don't share this worry.
We all know that USA is not just country. We know Russian ain't really country either. They're more of empires with bigger diversity than whole europe counted together. Still, as explained in just about every message, it's ideological choice to reject "person" or "individual" in his banal form. This includes rejecting the necessity to treat every person as individual - which they most often are not. They can be looked simply as perfect example of some mass where there are more common traits, common influenced, common motivators, than little differences. From that background (through acceptance or rejection) they may rise.
One may argue our gender, racial, national and cultural traits are imaginary, and simply people following the expectation (or observer counting only the expected + ruling out different) is what makes them true. Or that men and women are trapped in imaginary gender roles? And it argument means what? That people could be different, but aren't, under cultural reasons they couldn't really escape?
