Sign #1 - “If you’re a Spaniard, speak Spanish”
Sign #2 - “Speak properly. Be a patriot - Don’t be a barbarian. It’s a polite gentleman’s manners to speak in our language, that is, Spanish. That’s being a patriot. Long live Spain and discipline and our Cervantine language.”
These kind of signs and flyers were a common thing during Franco’s dictatorship, whose target was just to erase any other language that wasn’t Spanish - Galego, Català, Euskara, etc. Of course not being “a patriot”, that is, speaking any other language for example, was punished via an exorbitant fine, prison or even death.
The sad thing is that we’ve read the argument “if you’re a Spaniard, speak Spanish” not that long ago. Sheesh.
