People have an utterly bizarre attitude towards animals and meat. The delusion runs so deep, that when you become aware of it, its quite shocking to see the 'things' you once missed. Who walks past a piece of roadkill on the side of the road and thinks 'mmmm, that will be a tastey pie', and yet the security scanners at my local supermarket are decorated with marketing boards depicting prime cuts of beef. Right at the entrance, a hunk of meat, from a once living thing, dressed for camera and proudly displayed.
The marketing of meat (prepared, dressed, artifically modified and photographed) is so far removed from the original animal, there is a cognative disconnect between the death of the animal and the end product. You wouldnt stand by and watch a piglet get thrown in to a blender for sausages. So why is it ok, so long as you don't 'know' its a piglet?
