It's regrettable the way some livestock are kept, this however (vid in OP) is unnesscery and cruel and something you are doing, not something out of your hands. As long as you make a concious effort to deter from buying abused livestock meat/ect like buying free range eggs, I think you have every right to condem these sickos.
Well to them it's an act of everyday life, who are we to judge? Do you eat lobster? Do you know how those are cooked?
And some livestock my ass, unless you're buying from a mom and pop store, the eggs and meat you buy from walmart or your local grocery store is from a major livestock farm where the animals suffer tremendously. I can research and post some videos on how those work if you guys want.
With that said, I'm not a vegetarian, but I'm seriously thinking of only buying animal products from mom and pop stores, even if it's significantly more expensive.
