I think it depends about messaging. There's one aspect to saying "Hey, we are trying to be ultra-inclusive, and there have been members in this group that feel offended or excluded via the term "guys". To make everyone feel welcome, we ask you refrain from "guys" and use the more inclusive "folks", instead.". vs "'Guys' is a non-inclusive and harmful term. Please consider using 'folks' instead." I don't know how the Elm slack channel has broadcasted this messaging, but the first offers the benefit of the doubt and a chance to understand the situation / learn. The second is just asking to put people on the defensive. Unfortunately, I've come across the second type of messaging far too often, and it often just induces eye-rolls more than anything.
