I have definitely gotten the impression (as a very peripheral observer of the Rust community) that ideological diversity is not at all the sort of diversity Mozilla is interested in.
I wonder where that impression comes from? The Rust project is surprisingly diverse there and especially the moderation teams run the gamut from very progressive to very classic conservative.
We have a common boundary agreement (that's what the CoC lays out), but other then that, you'd be surprised of the number of opinions you'd see.
Granted, some of the very public figures are very progressive/leftist, but they also do their legwork for it and generally keep that on the side when they speak with their Rust hat on.
They did clearly state "given the context". The context being someone who, supposedly (I don't know, that was before my time and outside of my circles), had those traits.
So I think saying "by thinking anyone with differing opinions is Xist" is a mischaracterization of what was expressed originally.
We're not talking about "anyone with differing opinions", we're talking about a specific person who publicly denounced their coworkers based on their gender and sexuality.
