WHERE DO YOU DRAW THE LINE? BUMPER STICKER

Where do you draw the line on animals for food? How do you come to that decision? A pig is as smart as a dog,compared to a 3yo child for that matter in some instances.If I was going on aesthetic value a dog would seem more appealing to me than a muddy ole pig(no offence piggy's) If a dog tasted like pork?....China eats them by the tons,which I find disgusting and hard to imagine.Yet we sit down to factory farmed animals(pork,bacon,ham,chi​cken,lamb,beef,etc)without​ a secound thought as to the horror that meal has been through.Conditions similar to filthy puppy mills,then,transported in crates and cramped semi-trailers to be slaughted in front of one another.Obama has just okayed slaughterhouses for horses for human consumption,outrage,but these slaughterhouses have always operated for other animals,which we turn a blind eye to. Many animals are sentient,they are aware that they are going to die.There are many examples of this- http://www.youtube.com/​watch?v=LUkHkyy4uqw
