Localism
At a surf break, when the line-up is crowded, and competition becomes heated for precious few waves, scenes of hostility are not uncommon. Violence and threat are the ugliest manifestations, but they do happen surprisingly often for something so chill and harmonious as surfing. Localism is the term for brutish behavior stemming from protective ownership of a spot.
I’ve been wondering lately about this in light of discussion of RTM, and questions of involvement vs. ownership.
