The goal of hunting is to kill.....and, I like to kill deer. True enough, I do try to kill mature deer. But, that is just a decision, not a goal.
There is nothing wrong with Management, Farming for deer OR Trophy Hunting. They are all great fun for different people.
The line is crossed when one group tries to force their ideas on all the others.
That is simply my opinion. Everyone is entitled to their own.
That is your goal but it's not everyones. That was the case when people were subsistence hunters but that's rare these days. Most people evolve over their hunting careers. I've been at it for over 50 years and I definitely see things in a different light than I did years ago. I can vividly remember the first time I passed up a buck that I would have shot earlier. I got a bigger kick out of not shooting it than I would have from killing it. I still go most every day, but I probably won't even kill a deer unless its a 130+ buck. I could kill a deer most every day i hunt. Neither of us is right or wrong, just different strokes for different folks. I enjoy it much as I ever did just in another way
If you are taking a weapon and attempting to kill a deer, then we have the same goal. We may choose to select different criteria for the deer we kill, maybe not?
But, yes, the goal is to kill.
But, there are numerous other aspects of the experience that bring about varying amounts of satisfaction to different people.
