As you're probably aware, the partially autonomous Spanish region of Catalonia has voted in favor of independence and the Spanish central government has intervened to block it. I don't know enough to have a strong opinion either way. On principle I like the idea of self-determination, but I'm also skeptical of fragmentation, and I'm glad the Confederacy lost the U.S. Civil War.
I found Stephen Colbert's November 3 commentary below interesting and thought-provoking, especially for something on a late-night talk show:
For something non-political from Catalonia, see this truly entertaining flash-mob-orchestra performance of Beethoven's "Ode to Joy" from the city of Sabadell back in 2011.
