So what might a Russian teen think when they hear about USA passionately blabbing 6 Million genocide?

USA passionately blabbling about many things, but I don't think Russian teens care much about what USA propaganda blabbling about. Tons of that things does not match reality, based on lies or insanely hypocritical. Yet another thing just does not matter.

Fortunately, Russian youth got a good vaccination against Western propaganda virus on the example of their parents who survived 1990s, when all what USA government tried to push here turn out to be lies and cheating. From "free market" to "gay rights". It's hard to believe, but at the time of BLM shit, Western propaganda tried to push the same narrative in Russia too, despite there is absolutely no any ground for that narrative at all. Even rare African students who study in Russian universities laughed out on that stupid attempt.

Narrative about some special and worst of all suffering of jews during WWII will never find any ground here because it is hard to find a family in Russia that was not touched by WWII one way or another and suffered. And here comes jews who declare that they somehow suffered more and so have to be specially praised and respected for that. It's a clear invitation for unconditional GTFO for that jews with their narrative.
