This is a discussion I think we have all had from time to time. The way we handle it can either fuel their fire or undermine their objections. Just saying "It is my right" doesn't cut it. The one I have had best success with is based on the very reasons I decided to become a hunter some 25 years ago. It goes this way.
First I ask them, "Are you a vegetarian?" Most are not.
Then I ask them, "Where do you get the meat you eat?" I have found most have not put any thought into that. They say from the store, etc.
I then like to ask, "Do you think that way is better for nature and animals?" They always say yes.
Then I tell them that, "I know how you feel. I use to feel the same way. I thought hunters were destroying the natural world that I loved."
Then I say, "I learned that when I buy meat from a modern grocery store I am actually destroying whole forests and ecosystems. Let me explain. For there to be the store a portion of the natural world had to be destroyed. For there to be the meat a slaughter house had to be built so another portion of the nature was destroyed. For there to be the cow a farm or ranch had to maintained which consumed a huge portion of a forest or detroyed a whole ecosystem and all the natural creatures that lived there. Some actually have cattle packed into pens with no vegitation just being fattened up so they can be killed. To get the cattle feed other farms had to exist so more wild areas were lost to grow crops. Not to mention all the environmental pollution involved in all the processes."
Then I bring out, "On the other hand, when you choose to hunt you buy a license that helps support natural areas. Then you go into an area with a surplus of game and harvest (they like that word better) an animal for your personal consumption. While you were there you enjoyed nature and watched animals thriving in their natural environment. No forests cut down, no fenced in ranches, no slaughterhouses, no stores. Just taking a surplus animal from nature the way man has done for thousands of years"
I then like to ask them what they think about that. Sometimes they get the point right away sometimes I have to get more graphic with my description of the frogs and fish being killed as the ponds are filled in for parking lots and the squirrels, rabbits, deer, hawks and songbirds all losing their homes so they can have a hamburger.
If they say they understand but could never kill an animal so need to buy meat I tell them, "I understand, my wife loves wild game but trusts me with the killing part to do it the right way." I also encourage them that if they are going to purchase meat to do so from a smaller, natural type farm where there is less environmental impact. I also tell them it's healthier for the livestock and them too.
If they say, "Well why don't YOU buy meat from one of them instead of killing a deer?" I tell them, "If I had to I would, but I believe the most natural way is the best way and what is more natural than taking only what you need from natures surplus and doing what you can to protect the wilderness for all to enjoy."
Anyway, I have had somewhat good success with that line of reasoning so I thought I would share it with you. It would also be good to hear some other methods that have worked well for you. Thanks,
