So you say that your equivalent to an insect; ant or cockroach?
Just shows your naivety
IMO, not completely, depending on their amount or level of concisenesses http://en.wikipedia.org/wiki/8-Circuit_Model_of_Consciousness, it would be too cruel to kill an animal, if painlessly or not. and the method in which you slaughter sheep is a slow one, and thus brutal, not like the quick way the butchers and modern farmers do it, if they behead a cow, it usually happens so fast that the cow does not have enough time to feel any pain.
Well if you think that shoving a metal rod through the animals head is humane then thats your opinion. I dont think its because its quick for the animal, its mostly quick for the farmer.
IMO we do it the right way.
We feed the animal a little water just before, 3 motions through the 3 main veins. Nothing wrong with that.
