The "unhygenic" argument placed by muslims is ridiculous. The claim that other methods of killing the animal are unhygenic and Halal cleans out the blood was true......in 800 A.D.

We're living in 2005, You can kill your animal using the Shariah Law method, but please, don't tell me the food that we're getting from a store is unhygenic. Yes, occassionally you get bad food, but the percentage is so low its ridiculous to claim Westernized food is unhygenic. Back in the day, sure, but now? Through all the tests and machines meat is processed thru, it is VERY hygenic.
Even pork that has been processed through machines and tested by the Government has been proven to be very Hygenic, and more-so hygenic that what certian Muslims in 3rd world countries eat as meat.
Now, your other arguement about Halal meat being humane as it does not torture the animal, is relative. The arguement over what is humane and mannerful is very relative to the individual thats looking upon the situation. Some countries chop off hands for a crime, others put the death penalty, some have NO penalty. The original thought of chopping off hands for a crime committed, was viewed "inhumane" by some, but the practitioners viewed the complete killing of the body via a lethal injection as "inhumane".

In the end the animal is dead, tortured or not, the conclusion is the same. Your method of killing could be viewed by someone else as torture.
And there's nothing wrong with eating Halal meat in Sikhism, it's a foolish taboo.
