I guess the whole issue was never all that much of an issue for me, growing up with farming and ranching. Ranching, you raise cattle to sell to the market for folks to eat. You work your butt off to make sure the herd stays healthy, and you can't help but feel some attachment to those animals.
But their intended purpose is as food for people. And you can't have the food without killing the animal. For me, then, there's just no concern about "the way life is".
Bambi: Graceful. Pretty, in body and for the buck, antlers. There's just something about a deer that's more aesthetically pleasing to me than most other herbivores. But they're meat, and the meat tastes good. If you want to eat venison, ya gotta kill the deer. That's just the way life is.
My concern is for the health of the herd, not the fate of an individual animal.
Ethics? In general, it has to do with a quick, clean kill, minimizing suffering. That's why I make the effort to use a tack-driving rifle and control my "buck fever" so that I do the proper bullet placement. "Fair chase" comes in via not cheating: I don't hunt deer at night, nor hunt in any small high-fenced enclosure. I really don't care for hunting over such bait as an oat patch, for that matter, but that's sorta drifting off the fair chase issue. I don't want to get into the issue of fair chase and waiting at a water hole, either; after all, that's what the big cats do...
Last, I guess, hunting is a way of connecting with hundreds of generations of forebears. Sitting around the fire at deer camp, watching stars, visiting with friends: That's been going on for thousands of years. I'm not so arrogant that I think only modern ways have validity.
Only hunters and gardeners are "do it yourselfers" in providing food. Everybody else merely hires other people to do the dirty scut work for them. Think about that when you boogie on down to Ruth's Chris...
If I were a hostile sort, I'd ask the meat-eating anti-hunter, "What makes you so noble, since you hired a killer to do your slaughtering for you?"
