Labels, unfortunately, are a fact of existence. Since language was created labels have been used necessarily.
Without them we could not identify anything.
Car. Bank. Pencil.
How we use the labels is the issue. Do we use them for identification, humiliation, clarification?
Personally I don't like labels, especially in our world. There are too many, they are too confusing and they really don't help us. TV, TG, TS, CD, Cis, Poly (wanna cracker??

).
Just be careful how we use them among ourselves. Others will take care of using them against us.
