If everyone's default state is unlabled, then no, not labeling yourself isn't a label.
You're missing the point of the article by discussing given labels.
Queer is not the same as LGBTQ+ (queer is more overly political). My identity is both given and self selected.
Boy, girl, man, woman. Success, failure, virgin, slut, ice queen. Creep.
I'm sure you've labeled others with at least one and possibly been labeled with one you weren't happy about that didn't fit your identity. There are so many more and you use them without thinking.
If you decide to self label as a 'creep' or 'success' then it's relevant to this thread's discussion. If people just decide to label you as a 'creep' or 'success' then it's not relevant.
