My dear 'Native Speaker'.
Whilst we may all agree with you that a 'native speaker' is one who processes language without translating, the term 'native speaker' when used in EFL, ESL education has a totally different definition. Let me direct you to a www site 'eslcafe.com/jobs' where the term 'English native speaker' means someone born in an English speaking country with English as their 'mother tongue'. Just out of interest, please tell me how many 'English native speakers' are here (in Poland) because they are young (age??) are not experienced and can't get a job in their own country. Try for a job as a 'native speaker' and you will find that 'your place of birth' is the first thing anyone asks. Personally, I am multi-lingual and I 'think' in the language I am speaking or writing, but nobody would call me a native speaker of that language. I have 'native-like fluency'. I have been told on many occasions that you are only a 'native speaker' of you mother tongue language. And yes, as you may have gathered, I do have a bee in my bonnet about the term 'native speaker'.
