This is an interesting thread, and lots of personal experiences. If you're young and/or easily pass, it's understandable to be anger about pronouns, but if you're not either, then it's an I don't have an answer. Clearly to me, however, we make our choices, our demands, and if we choose to walk away from someone, we should understand and accept that we did for whatever reason we did, and not blame the other person for the whole issue or choice.
I don't like people using wrong pronouns or other inappropriate descriptions about people, and if it's clearly intentional, I'll be the first to speak up. I do think, however, we have to remember we're making the change and the choices, and also the demands of them. How many times or with some thing have we not agreed to or followed someone else's demands? And how did they feel about us when we failed them?
The hardest thing is to see ourselves, and maybe before we become intolerant with someone or about something, we should look in the mirror. And ask ourselves is it really worth the loss of the friendship or love of someone else? If yes, then accept it's your choice, not their problem. Changing doesn't make us better, just different, and staying the same doesn't make them bad, just the same.
