Don't get me wrong sadly there are plenty of poor hunting and shooting practices that go on. The idea of driving around in a comfortable 4x4, taking a few steps across the grass and then shooting something to my mind is not proper sport.
Yet pretty much what happens whenever there is any form of driven hunting, or even for that matter hunting from a high seat or stand. It's down to the hunter be selective and ethical.
Now when I took my chamois last year, yes I could have sat in a high seat, but I made it clear that I wanted to hunt it the proper way - ie on foot and in the mountains with a proper stalk. But appreciate that for say my father who is now pretty much unable to walk there may be fewer options and a highseat would be a perfectly valid way to hunt.
The late Don Heath, who wrote as Ganyana, in an article a few years ago asked whether big game hunting was a sport - his view view was that the classical interpretation of sport was that it must carry a good element of risk and challenge, other wise its just a past time or entertainment. I will find the article - have it saved somewhere.
Not sure if I would go quite that far, but I certainly think that with ethical hunting the odds need to be in favour of the hunted animal. If you watch the like of Meat Eater, Steve Rinnela spends a lot of time talking the misery and hard yards of hunting. To shoot a Moose in Alaska for instance usually requires multiple days of misery in the wet and cold just trying to find one. Hunting red deer in the highlands, especially hinds in the winter is proper hunting, so to my mind is stalking Roe bucks or shooting geese on the foreshore.
What is questionable is shooting geese over decoys on the only feed source for miles around, or shooting deer in winter again over the only feed source, or hunting with the aid of lamps / thermal or night vision.
There are occasions when for control measures such practices are required. To my mind these are not hunting, nor particularly ethical, but on occasion are necessary. But if good sensible wildlife management is carried on in an ethical and sensible manner, such practices should not be needed.
