Other forms: sectionalisms
Sectionalism is a partiality for a particular place, like when a US politician shows little interest in other countries or when someone who lives in Alaska only cares about policies and laws that directly affect her state.
As it's a devotion to just one section of a larger place, sectionalism can give people a somewhat narrow-minded perspective on the world. Sectionalism is a practically provincial devotion to one particular place, and it's usually a little bit irrational in its partiality. Of course, if you live in Hawaii or Paris, a little bit of sectionalism would be completely understandable.
