Wonderful topic for a session, @lucy!
Your suggestions sound valuable, but I would also like to also discuss how we get the balance between inclusion and free-form discussion.
As an example, there are some communities that are very sensitive to particular words, terms, phrases, gestures, styles, and other attributes for fear that they exclude people, but the policing of those attributes can sometimes be managed in somewhat sup-optimal ways.
While the spirit of inclusiveness is admirable, sometimes the way it is handled can actually act as a deterrent in which participants feel like they are walking around on eggshells for fear of saying something and causing offense. I have seen many good people leave communities for such reasons.
It would be great if we could provide some recommendations for how people encourage inclusiveness but also manage it in an optimal way.
