Gender isn't actually a thing in the first place? In the very instance of someone's life it is when a wowan gives birth isnt the baby a boy or a girl?There is nothing socially construct about nature and science. There is nothing wrong in saying good morning ladies and gentlemen. We are changing this because a tiny amount of people are offended. I am offended that people are offended, so do we change it back? No issue with people deciding to become a man or woman , there choice but , this is silly. As you say it's a tiny adjustment but there are bigger issues facing society than this.
