If I hammer my own thumb while doing some DIY, it's not nice, but it's not the end of the world. To care obsessively about similar levels of discomfort in animals seems to be a case of mistaken moral priorities.

I am very Aristotelian in approach - not in detail - so I always find I'm saying things that get people frustrated like 'It's a matter of balance and judgement'.
