How does labeling theory differ from other theories of deviance

I believe the answer is: A person will not be labeled as deviant unless his/her deviant behavior is in some way known to other people.

On top of that, the standard that considered as 'deviant' behavior must be the opposite of what considered as normal by the majority members of society.

This principle could explain why some people choose to hide their true nature/identities in order to avoid negative treatments.
