By agreeing to integrate the "Tamazight language" into its educational system, the perfidious and calculating Algerian state wants to annihilate the Kabyle language by creating a diglossia which will in turn create serious learning problems and cross-comprehension issues. Because this "Tamazight language" is full of neologisms, in addition to being an absurd mixture of several Berber languages, that often have no meaning and has no connection with the sociolinguistic reality for all Berbers. In the end, they all lose out.
