This for many people is what is most offensive about hunting—to some, disgusting: that it encourages, or allows, us not only to kill but to take a certain pleasure in killing. It's not as though the rest of us don't countenance the killing of tens of millions of animals every year. Yet for some reason we feel more comfortable with the mechanical killing practiced, out of view and without emotion by industrial agriculture.
