I probably should have been both more clear and more emphatic is Post #23.
There is subsistence hunting for survival. All other hunting, no matter how it's done, is sport hunting. Period. End of story.
The term came about as the actual need for subsistence hunting declined and the idea of handicapping oneself came to be. "Only shoot a bird when it's in flight" is one example. It's not law, but it's favored custom. (Doesn't apply to blue quail, though. The "run-run bird".

)
Seems reasonable to assume that the hunting becomes more sporting as one increases one's handicap--but that's still an individual judgement. After all, there are some folks who consider it a challenge to make love in a hammock, and even more of a challenge when standing.
So time goes on and folks improve their technology as folks have always done. Some like that, some don't like that. Again, so what?
We'll always have overly-competitive people who hunt, and others who have no interest in anything resembling what we call fair chase or even clean, ethical kills. That small percentage of all hunters, however, should not have us squabbling among ourselves over small differences in how we view the act of hunting.
I tend to look down on those who make all-inclusive statements about people's hunting styles when there is a difference from that to which one is accustomed. Stand hunting is uncommon in wide open country. So what? Walking hunting is uncommon in heavy brush and timber. So what?
Southern hunters and central Texas hunters, to my personal knowledge, are as likely to be doe hunters or even small-buck meat hunters as they are to only seek El Biggie, the trophy buck. In my home territory in the desert, we only hunt bucks: Too sparse a population to even begin to consider hunting does. You only spend the interest on your principal; if you spend the principal, you go broke. Does are principal, bucks are the interest.
And so it goes. It ain't much of a career, picking flypoop out of pepper.
