I don't think we're coming to an understanding.
You're (inadvertently?) twisting the phrase "not welcome", which I apply to behavior, to make it apply to people. If we can't agree on how to apply words we cannot use them to approach understanding.
Yes, and I believe that this attitude harms community building, education and adoption efforts. You specifically use the words "not welcome". Other, more welcoming projects typically don't use such language outside of a Code of Conduct policy document. I'm pointing out that I've been made to feel unwelcome and you're saying that is entirely harmless.
Do you see the problem?
