Humans have a brain....we use it to outsmart animals that aren't as smart. Now...unless you are hunting with a knife or spear while stalking your prey then you are taking advantage of the deer. Even hunting this way we are smart enough to kill some aniamls. The success will be lower but we are smart enough to kill a deer with nothing more than a knife or spear if we had to.

Anything above this is taking advantage of the animal some how. Camo, scent, calls, tree stands, blinds, food plots, bait, high powered rifles, modern compound bows, xbows, binoculars, rangefinders, scentlock suits, etc.....you get the point. Everyone of us picks the things we want to make hunting easier. Who's to say what's right for everyone? Don't get so smug and think you are somehow a purest for doing it "your way". Enoy your hunt...and let others enjoy theirs and stop worring about who's doing what right.
