It's patently absurd to judge bowhunters of yesteryear by applying today's standards to them. The whole process of bowhunting was in it's developmental years and - once again - what they learned then is a huge part of what has formed our code of ethics today.
The rest of our code has been formed by the anti-hunting establishment - a group of well financed complete idiots that no hunter ever had to deal with before the 1980's. We've had to really tighten up on our behavior to keep from feeding them ammunition.
In that way, the anti-hunting movement has been good for hunting.
If that is true ......... then you can expect in 30 years people to look back on you and I and say the same thing ?
