There are whole bunch of things, and people's attitudes toward them, getting mixed up in this thread.
Skill... of which it takes more to do something the hard way. It's easy for those with more skill at tracking, marksmanship, and so on to look down on those who are less skilled and who opt to hunt in ways that give them a better chance of success, given their skill level. (I drive a stick shift, but does that mean that those who don't aren't "driving?" I don't think so. Do I feel a bit superior? Of course.
)
Time... Not everyone has the time to be a purist. So if they use more modern technology, as a way to accomplish the goal faster, does that make them lesser hunters, or not hunters at all?
Sport vs. subsistence... One can make a case, I think, that the whole notion that hunting is a sport was developed by (wealthy) people who didn't have to hunt in order to eat, as a way to avoid the perception that they were just killing for fun. If you're hunting in order to feed your family, it's not a sport: you want to be as efficient as possible, while spending as little money as possible in the process. So on one hand, you won't think twice about things like baiting or hunting stream crossings; on the other, you're not likely to be spending your money on gadgetry.
Making a hunt harder than it needs to be is just as much a luxury as paying a large sum of money to hunt trophy animals on a fenced ranch. So the loincloth-and-stone knife crowd, in this day and age, is being pretty self-indulgent, IMO.
Purpose... if you're a subsistence hunter, then filling your tag is the main goal. For many who hunt for sport, the process is just as important as the result. For some, that means they value the time spent scouting and tracking at least as much as they value the actual kill. For others, the process is more one of, well, consumerism: having the latest and fanciest gear, the "best" rifle, etc. (OK, I admit... I'd rather be out in woods than hanging out in Cabela's, so, yeah, I look down on those folks a bit -- but they're spending money and helping the economy, at least.)
I have no problem calling a given method "hunting" if the animal being hunted has a reasonable chance of getting away; that said, I certainly find some approaches more attractive than others...
But bragging is repulsive no matter who's doing it, and I think most of us are sceptical about the actual skill of a braggart.
