I recently came across a new one with pronouns at work. Corresponding about a facility rental with a member of the local LGBTQ+ group, this person who is clearly female listen (no pronouns) in her email signature.
I am not sure what the expectation is for this, she also simply uses an initial for her name, which I've seen a few times recently among non-binary or transmen in my local area. My best guess is we are just meant to use the initial all the time.
X seems pleasant enough but man, my mind boggles at the need for special validation among so many of these young people. It seems designed to create a lack of inner resilience.
