8 One is a ritual sacrifice to glorify a false god and the other is more about what is permitted to eat, and a blessing for the consumer.
11 There is a host of differences. ... There are some similarities: ...
14 I know kosher meat, aside from being Scripturally clean, the animal is killed in a way that minimizes its suffering.
19 And halal killing maximizes it. Spiritually and biologically, halal is designed to put terror into meat.
My limited information focuses on the killing of the animal. Kosher butchers are required to use extremely sharp knives to minimize the suffering. Don't know if the cut goes through the trachea first or if it targets the carotid arteries along both sides of the neck. Severing the carotid arteries renders the animal unconscious in a matter of seconds, e.g. < 5, due to loss of blood pressure to the brain.
It is interesting to think back to ~70 A.D. and the Hebrew zealots holding out against the Romans at Masada. The 10(?) Hebrew warriors drew lots to slay their countrymen instead of falling into the hands of the Romans. The thinking is that they severed the carotid arteries on the necks of their compatriots/friends/family members.
Don't know about the conditions of the Kosher butcher's slaughterhouse. I do know that in American slaughterhouses, the livestock can smell the fresh blood, and that creates anxiety in the animals. American slaughterhouses use stun guns to the head (cattle) and carbon monoxide (swine) to render the animals unconscious before killing the animal. Poultry are electrically shocked unconscious before cutting their necks.
Hopefully some Freeper can provide details of the Halal butcher. I am under the impression that minimizing pain/stress in the animal is not a concern.
