Indoctrination or education?

 It is generally held that schools should be politically neutral. Here is a private Catalan nursery school  (Les Alzines in Girona) with banners saying 'Towards Independence' in Catalan and English. They are in a prominent position beside maps and other Catalan material. The school is connected with the extreme Catholic group Opus Dei.

 

 Here it is again in a tweet from a fortnight ago.

 Here is a classroom in a Barcelona secondary school (IES La Sedeta) showing an 'estelada' (independence flag) in the top right (YouTube)
