The “the community is unwelcome” critique itself does indeed feel like an unfair situation to me. Because it pretty much ends the conversation. If you push back on it, you’re being argumentative and just proving the point in the eyes of the complainant. And there’s only so much that folks in the community can handle “taking it on the chin” before they lose the ability to graciously empathize, especially if they strongly disagree with the assertion.
The “community” is definitely aware of these critiques, and many of us have been actively working on addressing it. I invite everyone to re-double their efforts to be friendly and welcoming, whether you agree with the assertion or not! For me, one concrete example is how I’ve been trying to avoid pile-ons here in discourse. I’m always open to suggestions on how we can do this better… and have been working with other communities on how to better moderate and how the discourse software itself could help us here (e.g., How to avoid an explosion of sub-topics in a topic - community - Discourse Meta, A softer slow mode: slow bumps? - feature - Discourse Meta).
So to that point: let’s avoid a pile-on here 
. Please consider whether your voice is needed here — this “room” could easily get too full and noisy.
