Most people don't identify as anything.
If they say otherwise it's because they have been asked a leading question which requires to know "what they identify as".
If you carried out a survey and asked people if they are make or female, I believe that the vast majority would not say "I identify as". Identify means to establish or indicate what something or someone is or has strong links with. So I don't identify as male and Aurora doesn't identify as female. I don't feel like I belong to a group of people, I do belong to them. There is no question, no doubt. I have the chromosomes that define me as male regardless of anything my head might think.
That's why people get fed up with the "I identify as" and CIS nonsense.
