Sarah Palin is against abortion and for hunting, and apparently sees no contradiction in this. Doctors, following the Hippocratic tradition of ‘first, do no harm,’ generally seem to have no problem eating animals. I know pacifistic meat-eaters, and I suspect also the occasional vegetarian war-supporter.
Hemingway's The Old Man and the Sea comes to mind as a pretty good example of how it's possible to honour and revere animal life while still taking it – although I don't have too much of a problem with killing for one's (immediate) survival. We live in a world that sometimes leaves that the only option.
I'm prepared to concede that sometimes killing is necessary. We do (with reservations) have a pretty natural impulse for survival; that's the way nature works. And sometimes it's them-or-us, and I think 'us' is usually a reasonable answer. However, the times we need to kill for our own survival are becoming fewer and further between, and I take issue with unnecessary killing of anything.
