Excuse the verbose, but here goes, since you make some valid points that I can’t explain in less words.
The educative system here is notoriously broken, actually. They tried to patch it a few times, but it was never good. The way I experienced things, we jumped from the romans to the industrial revolution and nothing in-between or after (due to educative reforms in the way). We didn’t even touch WWII, only local events. I am mostly sure older kids and younger kids did, but the way my peers did was a spectacular failure in terms of history and geography (outdated data in textbooks and such). We discovered just recently that a famous cup d’etat was a fraud, after believing it happened for the good half of a century.
Censorship and false information is commonplace here, even if we don’t have the fame of it like other places do. Even if English is a mandatory school subject, no one understands a word of English unless it’s people explicitly planning to leave the country in the first place or have relatives that require it, so most people is confined into tight Spanish-only (maybe with a latin-american mixed in, due to the language) circles and sites, and very few pursue anything out of there. So they can’t really go and educate themselves. Sites like Google and Youtube also have defaults to spanish-only sites and recommendations, and most people can’t be bothered to activate “show sites from any country”. Other sites force you into exclusive, dumber pages by geolocation, and several things are blocked, including popular viral stuff. There are also laws that facilitate censorship of spanish sites. I think they got recently covered in this site, actually.
It’s like a dumb version of China censorship, just lazier to the point of being barely noticeable if you get your news from outside sites like I do. TV is still relevant here, too, and it reeks of political meddling. International news are barely discussed in favor of local scandals that keep popping up and are given uneven and contradictory coverages, all biased based on the TV station and who the editors are in bed with. But the language barrier makes it harder to kill, and older people still has that “soccer team” mentality with their TV channel of choice.
This is not, of course, exclusive to this country. But it has that “half-assed Spanish quality” to it, so it’s all weird and crude like that.
Although, maybe, if we want to think of secret agendas, maybe it’s intentional they get so little coverage. Racism in form of exclusion? Like, pretty much hiding their existence? Those in positions of power are of highly religious upbringing, and it was religious nuts who tortured and converted or kicked those of Jewish faith out of the country, after all. I don’t think it’s the case (I hope not), but could be an explanation.
And about Zara, it was a locally-driven Spanish clothier until not that long ago. Given how it used to operate, the product might have been designed by a French couture (for the sake of example, I seriously doubt that tacky thing came from anyone with competence), but approved by Spanish bumpkins. I am not 100% sure on this though, so take it with a grain of salt. But I’d rather blame it on the distinct lack of information about the subject at hand. Seems the most logical to me being from here, but I can understand how the concept is completely nuts to outsiders. It was shocking enough for me, that I can say.
