On the surface they are very vocal about supporting 'inclusiveness' and 'non-discrimination' and 'tolerance'.
Yet they use a rather harsh and subjective code of conduct to control and police the members of their community.
Last I knew they even had a moderation team who doled out punishment without any due process nor any oversight of significance.
It's also quite common to see any comment here (and at certain other discussion forums) that doesn't paint Rust in a glowing light to get modded down, even when the observations made are completely correct, valid and legitimate.
As long as what you believe fits within the scope of what they believe, or corresponds to their narrative, then things are fine.
But beware if you happen to hold a differing opinion!
In fact I'm posting this using a throwaway account because I anticipate that members of the Rust community won't react well to my observations, and will respond with downmods.
