Antinonbinary
Antinonbinary or Antienby is an antigender identity in which one's gender feels as if their gender is the opposite of non-binary. This doesn't necessarily mean a binary gender, as binary genders may not be considered the opposite of non-binary genders in this context.
Antinonbinary is similar to anonbinary, ambigender, androgyne, and possibly femache and girlboy.
Counterparts to antinonbinary include antigirl, antiboy, antiagender, and antiaporagender.
