Please, the Spanish government itself would be all over her if she tried to fire the woman.
Kids here have their religion classes once a week during a certain period of the school day, which can instead be used for ethics classes or simply skipped by those who don't want it. This year Spain has reduced or refused to credit Catholic religious instruction in the school system, and has added over 100 hours of religious instruction in Islam (including in places that have no Muslims) and has adopted a textbook produced by a Spanish Muslim group, the name of which translates to "Getting to Know Islam." This is all part of their idiot PM's "Alianza de Culturas," which essentially means that Spain will probably go Muslim within the next 10-15 years, if nothing else changes.
Think you responded to the wrong poster, my friend.
