Why should we go for "fairness" when hunting for food? Using our brains isn't fair? Animals won't show any restraint when using their strengths to kill any weaker prey.
IMHO, fairness is necessary linked to bringing balance into the world. Using our brains is of course fair, but we should agree that there is much less brain work in the average modern hunter, drinking beer in a hideout and waiting for an opportunity to shoot a power rifle from a safe distance, than in any of the hunters depicted in the video. I of course cannot do what they do, but it was very humbling and moving to see such display of respect and fairness.
This is, of course, anecdotal, but I don't know any hunters who use high-power rifles from blinds. Typically, deer stands are used by bow hunters. High-power rifles are typically used from much greater distances where the shots are correspondingly more difficult. I'm not really into deer hunting (I prefer upland fowl), so my experience with the subject is limited. Either way, the "brain power" part of it went into the development of the tools, not so much into their use. Also, only an idiot mixes alcohol with firearms (or broadheads). Yes, there are people out there stupid enough to do so, but they are a very small minority (it tends to be self-enforcing). Hunting from a deer stand typically involves getting up before dawn and climbing up onto a rickety platform to shiver silently for hours hoping that a deer comes by close enough to shoot. That's why I'm not a big fan of deer hunting.
Let's also not conflate "fair" with "humane." As I mentioned, the area where I currently live is so overpopulated with deer that professional hunters have to be hired to kill a few hundred each year (it's truly astounding how fast the local herds grow). If they don't kill enough, even more will die by starvation and disease. If they were overly concerned about fairness, they wouldn't be able to kill enough deer in time, and that would be inhumane.
"You certainly show a level of maturity that is not common among typical hunters."
This is just plain stereotyping. I don't know how you formed your perception of the average maturity level of a typical hunter, but it clearly wasn't by actually interacting with typical hunters. Furthermore, I'm not even sure what a "typical" hunter is. That's kind of like a "typical" golfer, or a "typical" swimmer. I move around a lot, but I don't like to hunt alone, which unfortunately means I don't get to hunt very much any more. It also means that I'm always looking for new people to hunt with, and I've found hunters from all walks of life, often in very heterogeneous groups where the only thing they share in common is hunting.
If anything, hunting promotes maturity: when you teach a ten year old how to utilize a deadly weapon, and all of the ways you can accidentally hurt or kill yourself or others with it, and all of the rules for avoiding such mishaps, and all of the myriad ways you can get hurt or killed outdoors even without weapons involved, the sudden load of responsibilities tends to instill maturity in a way that less hazardous activities can't. True, some kids simply aren't ready for it as young as others, but most parents/mentors see this quickly and wait another year before resuming the lessons. Much like alcohol use in conjunction with firearms, it's rather self-enforcing: would you want to hang out in the middle of nowhere with an immature kid wielding a lethal weapon? Neither would I. Does it happen? Sure. Is it common? No.
I apologize if I offended you in anyway, perhaps I have been just unlucky with my prior shallow and brief interactions with hunters.
