Do you mind if I challenge your interpretation?

Suppose someone has their PPL, IMC, CPL and ATPL (All important licences for various different reason and status of a pilot) Would you say these people are 'amatuers' because they do not have their ATPL (Airline transport pilot's licence - to you, Airline pilot) instructor's rating? Afterall, very few pilot's actually hold the Airline Pilots Licence Instructors rating as not every pilot needs it as it's only required for instructing on the ATPL course. I'm not having a go at you, i'm just questioning your interpretation because being a pilot has many different levels and status regarding to licences and with the airlines, a pilots rank - First officer, Captain..etc.
