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.
You are right. FS would undoubtedly approve of deer hunting if they were penned up and hunted by illegals using dull machetes.
