"Is there a measureable difference between those that hunt nonhuman animals and those that pay others to breed, torture, and kill nonhumans and wrap chunks of their flesh in cellophane?"

I do think that there is a difference between hunting and paying others to kill, process and package for you. Simply put, I'd never hunt. I wouldn't be able to stalk someone with the intent to kill them. I just don't have it in me to do the stalking and causing them fear or terror, or the killing. While the end result is the same--unnecessary killing of a sentient nonhuman--the mentality is different.

Also, there's a difference in intent. When you hunt, your intention is to kill someone. When you buy a package of chicken's wings, you didn't intend to kill anybody. You're intending to eat their body parts, for certain, but in my mind you're not intending to kill.

I have a problem with people who delight in killing others, and for me that's the difference. And when you add something as draconian as aerial hunting of predators into the mix, I have an even bigger problem.
