Your question relates to sex when the discussion I was having about the title Mx being the norm is about gender
So the question "what sex are you" and "what gender are you" no longer mean the same. Why? Have our physical bodies evolved in some way that I'm not aware of?
If the freedom of speech is taken away
then dumb and silent we may be led,
like sheep to the slaughter. George Washington(1732-1799) First President of the USA.
