Well, I have an issue with YOUR definitions. Do you really not see anything wrong with the reduction of a living sentient being to a unit of production?! A century ago we would be having this discussion about slaves. Life is "nasty, brutish and cheap" in nature because survival is at play. A factory farm is a controlled environment for the enslavement of sentient beings. Two very different things.
If you believe that all( ANIMAL ) life is equal, do you believe that all death is equal? I'm against factory farming. When possible, I get my meat from wild game, or local farmers who love and respect their herds/flocks. I'm also a broke college student, so such ethical high ground is a luxury.
I believe that all suffering is equal and therefore we should do all we can to avoid it or minimize it regardless of species. Life preservation when having the choice. A plant based diet is not more expensive than a meat based one. Veggies are cheaper than meat.
