I'm sorry, but rather you tell our forum what "Red Leg would say" how about letting me speak for myself. I would also note, I feel no compunction to force you or anyone else to agree with me. But I do have a clear understanding about what I believe is ethical hunting; and that belief absolutely colors with whom I would care to share a campfire. And if anyone has a problem with that they are absolutely welcome not to invite me to their's.
I have no problem with fences where the fenced ground is adequate for the animal to not perceive it is confined. A lot of game ranges meet that standard. Those that advertise a particular animal or score typically do not. The big cats never ever fall into that category. They are raised by humans who they learn to at least partially trust. They are drugged and then they are released for some shooter to use as target practice. No game farm owner can afford great cats which are truly wild. Whatever this "sport" is - it isn't hunting. And I am convinced it is a practice which tarnishes all of us who love Africa.
And by the way, I don't blame the outfitters who offer this. They are simply feeding demand.
All depends on how strict your ethics are. For example when you hunted Africa I imagine each of those times you had a guide along with a team of trackers with you right? Some people would consider that unethical and would question if it is truly your trophy i.e. could you have gotten that animal without a guide and a team of trackers? Now I personally don't agree with this, but you can find people/hunters, mostly those who have never been on guided hunts, that think this way.
With that being said I kind of agree with you and I personally don't find shooting a drugged up zoo animal and paying big $$ to do it that appealing.
But going back to the tiger hunting in South Africa, from my understanding it is not economically feasible for game farmers to keep truly wild big cats on their properties due to price. Most people who shoot these lions in South Africa do it because it is a lot cheaper than a truly wild lion hunt in say Tanzania. The pen raised South African lions are 5-6 times cheaper as far I know. Now with tigers, if South Africa is the only place you can shoot tigers there might be a market here for game farmers to keep truly wild tigers, ie establish a breeding population and let them feed on animals on there own, and sell them for very high prices to very wealthy hunters. Money unlike with the people who hunt pen raised lions is of no issue to these people. I am guessing there would be a demand for this if it was the only place in the world you could do it.
