Professor 'Iggins -- I think you've got it...

All politics is local. Multiculturalism is a dichotomy. Liquids of differing viscosities and ionization attract or repel each other. The monolithic State is an unnatural state (pun intended).

Add those four facts of life together and one comes up with a dispersed and loose federal structure of governance allowing considerable autonomy downward as societies seek peace and equilibrium. Stability occurs through cooperation and mutual respect; like morality, it cannot be dictated and any effort to attempt to force it is a waste of time.

Unfortunately, that's a smack in the face to the progressive worldview.
