Interesting. Are you catalan by birth Aj? It does seem that any kind of ethnic and racial identity for white people have been systematically diminished from above, so i understand why things you say happen. I personally have gradually become more racist and tribal with every year since i realized that "my kind" of people, the best people, mind you, the people, who created all this civilization, are now methodically erradicated by hostile parasitic entity, whatever it is.
Whatever is the cause of catalan insurgency i don't know. Given than Spain consists or plethora of various sub-etnoses like castilians (madrdistgas), andalusians, barsques, catalans and whoever i don't remember obviously makes this whole conundrum even more complicated.
It's funny and relatable, because even my native country Latvia, which is tiny by both size and population, there are literally 5-6 various sub ethnic populations that behave and talk in their own dialect from each other and are of different temperament.
