There's Albert Boadella, who in a recent interview said nowadays he prefers to live in Madrid, song-writers like Joan Manuel Serrat (back in the day he was actually turned down for the Eurovision Song Contest because he insisted on doing the song in Catalan only).
I watched a video some time ago where this Catalan "intellectual" was going on about a whole load of major historical figures being Catalans rather than Spaniards from other regions. It sounded so historically preposterous with such crappy logic I really thought it was just a guy doing stand-up (and I'm not a naive person). But nobody was laughing though. Now wtf is that?
