Ship modeling isn't the Special Olympics where "everybody gets a prize" just for participating. Ship modeling is essentially an exercise in the pursuit of excellence. It categorically presents a hierarchy of accomplishment existing on two planes: 1) the individual and 2) the general. Every model is a statement of its builder's abilities and accomplishments and will always be judged against 1) the builder's own personal standards and 2) the general standards of the larger ship modeling community. Anybody can judge the quality of their own model on the basis of their own subjective standards. Everybody judges the quality of somebody else's model by far broader objective standards.
I stated a simple opinion: "If one does not wish to learn the proper terms, they maybe they really should consider another hobby." It applies to any hobby or endeavor of any kind, for that matter. If you don't want to learn "weights and measures," maybe you should really consider a hobby other than cooking. If you don't want to learn the rules of the road, maybe you should consider a hobby other than auto racing. If you don't want to learn to read music, maybe you should consider a hobby other than piano playing. If you don't want to learn to identify different species of wood, maybe you should consider a hobby other than woodworking. If you don't want to learn to identify the various bird breeds, maybe you should really consider a hobby other than birdwatching. And, if you don't want to learn what the various parts of ships are called or read and understand their plans, then maybe you should really consider a hobby other than ship modeling.
How is the statement, "If one does not wish to learn the proper terms, a language unto itself, to be sure, then maybe they really should consider another hobby." at all "arrogant?" It's not born of arrogance, but rather of experience. If somebody isn't prepared to learn proper nautical terminology or read lines drawings, they will most likely encounter difficulty and frustration trying to get very far as a ship modeler. Do you dispute the proposition that the more one knows about ships and ship building, the better ship modeler they are able to be?
