So, according to you, the Spanish constitution is nonsense:

Article 3

1. Castilian is the official Spanish language of the State. All Spaniards have the duty to know it and the right to use it.

2. The other Spanish languages shall also be official in the respective Autonomous Communities in accordance with their Statutes.

3. The wealth of the different linguistic modalities of Spain is a cultural heritage that shall be the object of special respect and protection.

No, officially in Spain the language is Castilian. However, according to the RAE, it’s also called Spanish. Indeed the RAE recommends the use of “español” (Spanish) [1].
