I don’t use the name on my birth certificate day to day and I bet that at least three quarters of the people in the world born “Michael” don’t either. I have walked this earth for fifty years and nobody ever mentions that to me, or any Bob, Rob, Pat, Dave, Sam, Jay, and Kat out there .
If you’re getting worked up about chosen names but not married names, honourifics or even nicknames, what you're really getting angry about is that people you hate are allowed to make choices for themselves.
