Sorry to burn down your straw man, but the overwhelming majority of "Rust evangelism" points out that Rust is not always the right tool for the job. The intersection between people who write both Rust and Go (for instance) is substantial, and people in the Rust community (more precisely: communities) go to great lengths to point out that it's not an either / or proposition. Most of the RIIR! hyperbole is something that happens to the Rust community, not on its behalf.

This seems somewhat at odds with your denunciation, mere sentences ago.
