I think we should go even farther with our euphemisms and call it "harvesting a resource".
I love meat, even though I consider killing animals unethical, which makes me a hypocrite. Still, I think the least we can do is call the process "killing an animal".
Also, ethics aside, the comment above was referring specifically to processing, not the act of killing. Killing is comparatively fast and far less messy. Butchering/processing a 300lb carcass is where the real effort lies.
I would hope that everyone understands that creating a final meat product involves killing, but we shouldn't trivialize the process requirements just to drive an emotional point home.
I haven't done larger animals from the killing but have butchered large cuts of meat. It is a time-consuming process while being physically tiring.
