No, I never said that Catalan is a dialect, it is indeed a language.

But Catalan nationalists are even trying to remove all Spanish from the education [1][2] even by disobeying court sentences.

If you compare the situation between Catalan and Galicia. You can see it clearly. Galician is not used by most people nor politicians as a political tool. Catalan is sadly being used as such.
