Blah, Blah, Blah. None of that is relevant to the point that eventually you will blow the headshot and watch a deer run off. Doesn't matter who owns the land, who owns the gun, how the Indians did anything (by the way how many headshots do you think they took with bows? Also, I happen to be Arapaho so I qualify as an Indian) or what type of privilege it is. None of that will mean a thing to the deer running off with its jaw shattered while you watch the smoke clear.
And 15 deer isn't really a lot of experience. I'd killed that many before I was 17 years old but that didn't make me an expert. Perhaps when you have more experience you'll understand why no really experienced and serious hunters advocate the shot you love. They have all seen it fail and one day you will too. Perhaps you're just too dense to see the point I make.
