There are two sides to every coin.
I will defer that to any Spaniards who are on FR, as I am frankly a bit ignorant of internal Spanish politics after about 2004 or so.
I do know that Catalonia has a large muslim population that will be even larger after the exit. I had friends that spent a few years in Barcelona, and they were rather concerned that the area was going to be under muslim law sooner than later
Not to mention the fact that “Catalonia” extends into France, and I doubt the Basques will remain.
Great time to be alive for a history nerd, bad time to live through.
