Nowadays there're enough (& different) places to hunt for every kind of hunter, for every ethic and for every pocket.
I always said that if it's a legal way of hunt is OK for me, even if this way I don't like and I'll never practise it.
Mainly, I think the "right" way of hunting must be learned. Nobody hunt after 20 years the same way that we do at the begginin, almost of us now we want to spend best moments while hunting with nice mates instead trophies.

In the early 90s I made several 21 days safaris in Africa taken more than 20 animal each, I wanted them all

, now (after more than 15 safaris) I enjoy a lot traveling to Botswana just for an elefant or spending 15 days in Alaska trying to get a Brown Bear.
I don't like fences but we will never be free of it, everyday there're more and more. Southafrica is a big ranch like almost Namibia and South Botswana, even Tanzania is going to "sell" ranches along the country.

I think every hunter must be Ok with himself and with the law, anything else doesn't matter
