I think it is because people are so far removed from the actual process of killing. I do believe that trophy hunters and trappers fall into the same category as meat eaters. Each of them is responsible for the death of an animal (or the demand for that death) and then take the part they want. Some want the exterior for 'art', some want the fur for clothing and some take the meat for food. In each case there are alternatives.

To each their own but I am an animal lover and lifelong vegetarian.
