d) the English way of slaughtering animals is to stun them first - this way they are unconscious when destroyed and totally oblivious to what is taking place - and they are then quickly and humanly destroyed
e) the halal way of slaughtering is to cut the throat of a totally conscious animal and leave it to die slowly and painfully - surrounded by other suffering animals - this is WRONG
That's the question of Kasher and Halal and in general the way that a hygienic rule becomes at the end a religious absurdity.
All this came from Ancient Testament and 2 laws :
1. which forbids to eat an animal that you found dead.
2. which forbids to eat the blood of an animal.
The 2nd was an irrational taboo, the 1st a sanitary rule when no one could guess the cause of the death and a protection against plagues.
But now it became an obligation to bleed a sheep alive, while it would be possible, I suppose, to stun them at first and then make them bleeding. But religion is sticking to the form of laws and forgot their real aim.
In Germany, some Länder started to ask to slaughter houses for Jews and Muslims to stun beats before killing them but of course it had no success : God is supposed to NEVER change His mind
Now concerning slaughter houses in general, animals are supposed to NOT suffer but most of the time it is wrong : they are badly convoyed, they are afraid, they smell blood and hear other beats crying, and often slaughter houses do not care of rules and kill them when they are still alive.
And of course, before that, the condition of their breeding and feeding is a shame. There was a good book about that : "Eating animals' by Jonathan Safran Foer.
I am not a veggie. I am for a more expensive meal from animals which were bred and killed in the best way. I always buy 'biological' eggs and meals. We do not need to eat meal every days.
And concerning poor people, States have to give them free food instead of money so they won't waste it buying the last TV or Iphone…
I have a great many Hindu friends and LOVE their food

The last Lent I cooked a lot of Thai and Chinese recipes. For the Lent 2015, I will adopt Indian veggie recipes, they are great with many scents and spices.
