Correction, you are not a trader; you are a hobbyist!
Nah, hes right. You just have some superiority complex and playing on semantics of the term, but thats something you need to work out on your part. A trader is someone who trades. A trader says nothing about one's profitability. E.g. you can be a 'failed trader' and lose money, or 'super trader' and bank the bucks.
Reminds me of when 'professional engineers', but often only those who have a BSc in engineering, get angry about train conductors being called 'engineers' also and go on a hissy fit. Who cares. Its just a term. Learn to live with yourself and stop worrying about silly stuff like what a term means.
