It seems you missed the point of our socratic dialogue. it isn't just gender that matters for the purposes of impact analysis. You have to consider things like cultural appropriation, ageism, and all other kinds of experience discrimination that people go through. for example, you are advocating for the use of y'all as a common parlance of a group of people. Did you stop to consider the impact that would have on people from the south who feel that is a cultural appropriation? did you stop to think about the impact of the word mates on people from Australia? The impact on gender fluid people is not the most important thing in the world. You have to consider the impact on everybody incoming to a cultural consensus. You don't simply get to change words and start using words that offend other people.
