I for one was not placing judgement on Miley Cyrus. I'm only trying to understand what she means when referring to herself as a "nothing". Miley was a former child star before she became a popstar and is the daughter of Billy Ray Cyrus, so her life has been in front and around cameras. She and controversy are no strangers as well. These are the reasons why it's difficult for me to take what she says and does seriously. I will give her credit in regards to how well she turned out as an adult. There have been many former child stars who ended up broke, emotionally disturbed, addicted to drugs or even dead due to suicide or a drug overdose. She's certainly in much better shape than those people.
If Miley turns out to be a non binary, than I'd like to see real evidence of it. I would want her to adopt a more gender ambiguous image and even include non binary themes in her music. The climate is ready for it. Keep in mind that we had Boy George more than 30 years ago, so yeah .... the time is right for an out of the closet non binary.
