It is one thing to hunt deer for their meat and then eat them, it is a totally different topic if people are killing endangered animals, not eating them and only harvesting them for their ivory. I also am disgusted by "trophy hunters" and "big game hunters" who don't actually eat what they kill. If you are going to kill it, then you should be eating it. End of story.
And killing an animal for its ivory - and then using that money to fund terrorism, well that is so wrong it boggles the mind. Think before you buy anything made of ivory.
