He isn't. His explanation in two posts above is that corporate farms are ok, and he lets bow hunters shoot his deer in exchange for venison. But in all his posts he derides what he calls "sport hunters". Frankly, I think he's just some clueless half-drunken fatso trolling for flames. But that's just my opinion.
Analogy fails, unless he/she/it thinks that an animal being pent up in a cage from birth pumped full of antibiotics because good hygiene is far too expensive, and having its life ended by having its head hacked off by a minimum wage illegal who likely lost the compassion to kill with one stroke on the second day at the job, is better off than an animal living & running in the wilderness as God intended, with its life ended painlessly with a clean shot in the chest.
