While I don’t understand gender politics, alternate pronouns and labels, I long since realized that it doesn’t matter. I’m all for everyone living their lives their way with equal respect. You do you, and be the best you you can, whatever you that may be, and I’ll be happy to call you friend
You have to start with local laws. They’re different depending on where you are. Including city.
