The thing that will kill hunting won't be crossbows, or modern inline muzzleloaders, or supermagnums with high powered scopes,or even anti-hunters; it will be hunters who would rather fractionalize and fight each other than fight those who would take away our ability to hunt.
I don't care what weapon you choose, I don't care if you use dogs, I cringe at the thought but I don't care if you bait. What I do care about is how you treat the land and how you honor the game.
I have hunted all my life. I have used recurves, compounds, crossbows, flintlocks, inlines, handguns, shotguns, and rifles. I am now learning to use the longbow.
But that longbow doesn't in anyway make me superior to the rifle hunter. I have taken deer at 4 yards with bows, shotguns, muzzleloaders, handguns and rifles. In my entire hunting lifetime (34 years for deer, 39 years for small game), I can count the shots that I have taken at game farther than 25 yards on my fingers. I can also say that I've missed more close shots than far.
If we don't pull together as hunters, we will lose the fight to keep the tradition of hunting alive.
