I never claimed to be an expert. I am admitting now that I am somewhat ignorant as to what the exact definitions are, but from what I understand from what my NB friend explained it is that if you transition from one gender to another that makes you trans. NB are neither gender so there was no transition between genders.
I guess one could make the argument that they transitioned from being gender-labeled to being non-gender, but IMO that’s a stretch in an attempt to label NB people as trans.
That being said, there is nothing wrong with being trans. I was just trying to make a distinction as was explained to me by a NB person.
