There is no need for generalization, there are many people in the community that respect and enjoy other languages, and most people also frequently use Python and R for most things that Julia is still not mature enough. But it's certainly hard sometimes for people who learned of powerful non mainstream languages, having to see people putting an amazing amount of resources and effort to provide every functionality to mainstream less powerful languages that would be almost free in said powerful language (be it syntax extensions with macros, high performance dynamic code without using FFI, parallelism, better compile-time checking...). It's probably what Lisp users had to deal with for 60 years now. Or more recently people who learned Rust but still have to deal with a world of C++.
