I honestly haven't found this to be the case. There is a constant denial that some people might find Rust difficult (with a very strong implication that if they do, it's because of inferiority on their part), and extreme thin-skinnedness towards even the possibility that Rust might not be for everyone. Indeed, a bluff assertion that it is for everyone is part of its official tagline. The community keeps up a surface politeness, but it always looks to me that it achieves this by keeping a tight lid on dissent (or appearance thereof).
