I don't have much to say about this but this piece ("safe spaces and competing access needs") and this discussion ("Safe" isn't a monolith.) have been rolling around in my head a lot, and I thought you might like to think about them too. Especially if you have responsibility for any shared physical or virtual group or venue that has a Code of Conduct, and especially if anyone in it has ever suggested that particular words or topics ought to be off-limits.
