I know plenty of 100% ethnic Russian kids who simply don't speak (usable) Russian when they grow up. Just for studying in a local or English school and integrating well. They can speak Russian on the level of 7-year old at 15, to speak with their grandmother over Skype, but never use it apart from that, replying their parents in English at home and speaking English to each other at school. So this is absolute bs that kids don't integrate well. Communism is nonexistent to them: it's just not on their mind map, many heard nothing about it beyond Reddit "political compass" memes. They see Orthodox Christianity as elaborate even if very boring cosplay. They don't "see" LGBT people simply because they are 100% norm and nothing to pay attention to, no one giggles at gay couples the way we did as kids. Many never been to Russia although they still hold passports simply for having no interest in that country. No negativity too - it's just not their life story.
