Sport fishermen, sport charter captains, and commercial fishermen.
I don't put the sport charters in the same category as sport fishermen because they are also selling a product, their services.
You are right, at least three different groups - and only the enviro nazi’s and the sports fishermen are easy to pin down from an ideological standpoint. That’s clearly left v right. The commercial guys, the charter guys (you are right, a hybrid) and others are all in a fuzzy ideologically impure middle ground.
