Surfing and “indigenous” are terms you seldom hear used in the same sentence, especially in the context of the continental United States. When we talk about Hawaii surfers understand about Native Hawaiians, who are usually referred to by the euphemism “locals.” Any surfer who’s ever been there is painfully aware of the tension between “locals” and haoles, and those with even the most cursory of historical knowledge know that the tension stems from a history of American imperialism against the independent nation of Hawaii.
Those with more advanced knowledge understand the reasons why the tension persists. People don’t respond well to military aggression, especially when the historical fallout is the inability to live in your own homelands or to be adequately housed and fed due to unending foreign invasion. To say nothing about the history of forced assimilation, land theft, and environmental degradation caused by a century and a half of economic imperialism from big agriculture, tourism, and militarism.
