Everyone saying that's cruel and then going out and having a nice burger, a piece of bacon, or chicken fajita is a fucking hypocrite. Try to educate yourself on how "food" animals are raised and slaughtered in the western world.
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.
And eating meat ect is an everyday act of life, this is just for pure enjoyment, that's the difference between this.
