I agree with Blue's sentiment. People have been carrying out incantations and peddling that their gods require certain ways of doing things since time immemorial with many gods and religions. Goodness, once human beings were sacrificed as a requirement of deities/idols according to their adherents. Maybe in a way some still are as murder by stoning is mandated by the Abrahamic deity for certain things like adultery.
Incantations and mumbo-jumbo don't cause pain. They aren't the important part. What is important is that extra suffering should not be inflicted on sentient animals needlessly because of the 'requirements' of a religion. Some have said that the animal is stunned (in this country anyway), but less so than an animal not killed according to this religious practice. The meat industry itself should to be run as humanely as possible. You hear dreadful stories about general brutality around abattoirs and stunning not working for all animals. Also the conditions of animals in general with low or absent welfare standards and intensive farming. Dairy industry as well. Animals should be killed with the least suffering as possible. That should be the only diktat in force. In fact the whole sector should be tightened and animal welfare improved as much as possible, never mind trying to justify lowering the bar.
There are a lot of people saying that people who don't want to eat meat killed in this religious way are being unreasonable (at best) and trying to smear and dismiss objections as Islamophobic. I think people are entitled to not eat meat killed like this if they don't want to. And certainly not unwittingly, with food labels omitting to show it is killed according to a halal method.
Would people actively choosing halal meat be similarly unreasonable to object if an additional incantation to another deity/idol was also said over the animal being killed? Say, a nice little prayer to Ahura Mazda/Ganesh/Ron L Hubbard accompanying the prayer to the Muslim deity. If they objected, that would be just as racist, and many things 'phobic'. Those other prayers are just words too! Importantly, to correspond, these other dedications would not shown on the label.
It is bizarre how people not wanting to unwittingly eat meat killed with incantations and a lower welfare standards mandate are the ones being called iffy and seem to have to justify themselves.
Religion as a life philosophy is fine and dandy when it drives you to be the best human being you can be and live 'the good life. When you claim your 'deity/idol' demands you interfere with others and cause suffering, it should be curtailed as it ends up being Fascistic and is just another malign ideology. No story should be indulged to that level.
