I think his comment goes more in the direction of "Pythonistas" or "Rustaceans". When I coded in C/C++ about 15 years ago I never felt like a part of a "C" community, same the last 15 years I coded with Python (and Java), I'd never consider myself as a "Pythonista", even though I love the language and the effort everybody puts into making this language so useful as well as learnable. The Rust community is also really helpful and well structured in the sense that you know what to expect from a contribution (like a crate), but I'll never label myself as a Rustacean even if I'd start using Rust as my primary language. These "groups" seem strange to me, almost like a cult which I feel is out of place. Like a group of Americans learning and using the Italian language calling themselves "Italians" just to point out that they have a special relation to that language which others don't have. The analogy doesn't really work, because there are no such person's like born "Pythonistas", but it somehow illustrates the vibe these groups apparently want to irradiate. I love the languages for what they are, and the love and effort the communities put into them shows more through the language itself than through a label a community gives itself.
