There are two uses and types of labels and you are ignoring the one to which I discuss in the article.

"Defining identity according to labels is the instrument of oppression. Oppression works by dividing people into groups and recognizing one group as having rights and all other groups as not having rights. At the core of oppression is bigotry which creates labels to designate groups and assert power over them."

I don't see why you ignore this and focus on the other use and type of label.
