I can provide some insights about immigrants Russian boomers, or at least the overwhelming majority of the blue pilled ones.
One characteristic of such people that I have observed, is that they are at least in part to blame in the abandonment of traditional Russian culture in favor of Soviet/Western ones. I say this because many of them grew up in households where the Russian traditions were still held. So preserving these traditions would have come naturally to them. Why didn't they preserve these traditions and pass them down to the later generations? They made no attempt to preserve the culture. Even some boomers who grew up in Orthodox households didn't preserve their religion nor pass it down to the next generation.
Many of such people have adopted the Soviet, Ukrainian, Federation, or American identities, instead of the Ruski identity. They have discarded the identity of the Ruski people, of their culture and civilization, in favor of artificial identities which are based on a loyalty to the state, to the made up country that they are residing in. They would say, for example, "we are the Soviet people, we are not the Ruski people."
Whenever I talk about the history or culture of my people (I wanted to say our people, but unfortunately that would be a misrepresentation), with the boomers who came from the territories of the former Russian Empire, they wouldn't take it seriously. They would say stuff like, "the Russian Empire collapsed long ago", "you live in the 21st century", "nobody wants to hear about that", "your culture doesn't exist anymore", or even "your culture never existed at all". Such responses throw me into dismay, how can old people say such things?
They have no sense of national identity, it seems. They didn't strive to cultivate the national identity and it's associated traditions within their families, nor to pass this treasure onto the next generation. And they ridicule people who in fact indeed do this.
I think that their rejection of traditional culture maybe a justification of their actions earlier in life. These people grew up during the Soviet Union, when the communists ordered to abandon the Ruski identity and the Ruski culture, these people complied. So they have to save face all their lives to justify their actions, why they so easily got rid of their culture, similar to how people who took the vaxx. Instead of admitting their error, they doubled down on it, becoming more cosmopolitan than the young people.
That's disappointing, because in the Russian traditional culture, elders were very well respected, they were supposed to be very wise people, the keepers and teachers of tradition. However now we young people have to be our own elders, or we have to find elders on the internet, YouTube, and various podcasts. We have to search the internet for bits and pieces of the Ruski traditional culture in an attempt to restore it, because the boomers discarded what they had given wholesale.
These are my observations about Russian immigrant boomers. Keep in mind that immigration attracts a certain kind of demographic though.
