Further, I have a prejudice in that I take the term "native speaker" to mean that the language is an idiom that one grew up with and used extensively (thereby gaining fluency) in the regular course of the day (in the family circle, in school and with schoolmates, in other social interactions).

At last, I understand how you could persuade yourself that there are no native speakers of Occitan.

If it is necessary to "speak it in school and with schoolmates" to be a native speaker, while living in a country where its use in school was banned for a century, then by definition, there are no native speakers.

Very neat, logically speaking.

Also very totalitarian.
