A chat seems welcoming as long as everyone expresses the same opinion. When a dissenting member receives jokes and silences.
I propose to evaluate the quality of the group through the way it handles a respectful difference. In the example, a moderator asks to discuss the topic without classifying the person.
Belonging and uniformity do not coincide. A useful link should leave room for a change of idea, a rejection and the possibility of not participating in every initiative.
