The word discriminate means simply to tell apart despite its negative connotations.   Yes Labels were made to discriminate, that is in essence the definition of a label.  However, a lot of time it is OK to label people.  If someone is labelled as a drug dealer, chances are even if they are clean cut and sharp, you would not want a family member to marry them without knowing that knowledge first.  I agree negative labels are sometimes thrown around too much.  But that shouldnt allow us to get rid of labelling altogether.
