Just seeing your reply now and wanted to say that I really appreciate your humorous self-reflection. Too often we just argue aggressively against the others standpoint without any self-reflection of our own (I've certainly been guilty of it).
Also the idea of smaller units for creating a closer feeling of belonging is something I've been thinking about quite a few times. I think countries/nations etc. try to use patriotism and a us vs them (because there is often not enough real connection otherwise) mentality to artificially create this.
