I read on Wikipedia that klezmer music was banned in the Stalin era USSR. Of course, you can easily find klezmer albums recorded in state owned studios in the Stalin era USSR. Pointing this out is "original research", which isn't allowed by Wikipedia. Instead you have to use a so-called reliable source, which means any dumb shit published by someone like Anne Applebaum in the Atlantic is just fine. I advise against using Wikipedia for anything. Even a straightforward fact like a date of birth isn't to be trusted unless you're planning to dig through all of the citations.
I do a lot of ranting in front of my kids, and when we're confronted with obvious bullshit like a bunch of people having to live under a bridge, I make sure to conclude the rant by telling them Stalin would've dealt with the people responsible for this.
I also tell them that in this family we talk to strangers, and then model that behavior. We spend a lot of time learning about the lives of people around the world and the collective accomplishments of the people in maligned places like Appalachia or China. We study foreign languages and speak to people in their native languages. As a general guiding principle my wife and I have agreed that we want our kids to grow up with self awareness that they are part of the workers of the world.
