Which part of my argument do you have an issue with?
Your definitions. A concentration camp is a device used to achieve a political end, the destruction, complete destruction of a group of humans, for no profit or reason other than politics. A farm, even a factory farm, is an engine of PRODUCTION. It is the result of market forces acting upon those who at one point (And some still do) cared for their animals with love and attention, under divine command to be good stewards of the earth, as the apex sentient beings. All life is not equal. Life in a meat farm is nasty, brutish and cheap. But no more or less so than nature is nasty, brutish and cheap.
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.
