What word would you use to convey the concept of ethics, manners, adherence to rules, self control, you know, all those things that hunters (in the US) incorrectly call sportsmanship?
All those misguided souls use that word to mean something, a collection of ideas and ideals that they associate with hunting, even if you do not. My saying that they view these ideas as indivisible from the activity of hunting is not just my opinion.
I feel like I have said that lots of people say the sky is blue, and you are saying that this is just my opinion and I am wrong because they are wrong. We both know that the sky isn't blue but just appears blue and the how and why is fairly complex, but people still say the sky is blue.
I used the term "sportsmanship" because it is commonly used to describe a concept that is used as a metric that people can and do use to rate how objectionable or ethical certain hunters are. You have disagreed with my choice of word, but have not offered any alternative word or metric by which anyone can or does rate hunter behaviour.
