Why do you need to massage what is being said so much? If you believe in your message, then just present it honestly.
Obviously it would be a case of saying "normal gender", or if someone asks how to describe a person's gender, they can simply reply "normal".
You're pretending that there are issues that simply don't exist because you want to force people to use the word that you want them to use.
Just be honest and stop trying to manipulate people.
