It's applies for many programming groups. Those like to live in their realm, one where that their language is the greatest and thou can't be spoken negative about.
Just try mentioning C++ to a bunch of Go programmers or Python to a bunch of Rust programmers.
Not to say there isn't crossover but it's all ironic really, as most languages were crafted from C.
What a completely unnecessary thing to say in the middle of an otherwise reasonable post.
