This one is easy. Predators in the wild have their incredible sense of smell, speed to run their prey down, strength to kill them with, sharp teeth, fur to keep them warm, etc... Why not call foul that predators hunt in packs. Her question is beyond silly.
The answer is that you and I have all the disadvantages compared to the prey we hunt. We increase our odds to ensure that we can make close clean kills. This respects the prey and ensures we make as many clean kills as possible.
No other answer needed.
As for offending them. Let em have it, bunny hugging morons need to know they are silly and wrong. As well a hypocrites of the worst kind, the self deluded kind! If they drive cars they kill bugs and animals, if they wear leather they kill animals, etc, etc, etc.... We all kill animals, every last one of us. If they want to stop killing animals then quit breeding more people!
Human population and urban sprawl is the biggest animal killer of all. The problem is most bunny huggers don't mind that they cand rive along killing things, wear leather belts and shoes, eat eggs, step on bugs, poison mice, the list here is 1,000 pages long. Most of them assuage their conscience by hiring other killers to take care of their killing for them.
Molly coddling or sugar coating this subject is exactly why we are where we are. Stop the PC stuff and tell them the facts. When an idiot speaks and no one corrects them, then they think they are right. Anti's are free to have their feelings and thoughts, what they are not free to do is push them off on you or anyone else. They are anti's. The fact that you hunt already offends them, sugar coating it is playing into their game.
