[I]n the wake of the growth of the animal-rights movement, there has recently arisen a hitherto unfelt need to demonise and demean our non-human victims - and those who try to help them - now that our previously well-nigh unquestioned right to kill and exploit them is being challenged. Bloodsports enthusiasts, for instance, currently spend a lot of time cataloguing the alleged depredations of our victims on the environment. Recreational animal-killers go to extraordinarily lengths to avoid admitting that they themselves enjoy hunting and killing other creatures for fun. But then until a few years ago such rationalisations seemed scarcely called for. Selfish DNA had honed our intuitions so that the most agonising bloodshed seemed simply "natural".
