Well, sure, it can be just a coincidence and that woman decided to talk about Stalin on her own and it wouldn't seem strange to a Westerner.
However it does look strange to a Russian, because frankly, I've never heard any Russian bringing up Stalin name in a casual discussion, unless answering a question specifically asked about Stalin. Perhaps that was one of such occasions and the question was omitted in the article as "not important"
And I don't think using Stalin, Chechnya and immigration in one article is merely a coincidence, and that's what Westerners want to hear about Russia, because it fits in the scope of public knowledge. The author just missing ballet and literature here, or maybe it was edited out![]()
