Nice to know that Patsy is prepared to pay for orthodontic work on an elderly stag!
People and animals are different. For good or ill, we eat animals; we don't eat people.
We have also changed the natural habitats in the UK so dramatically that we need to intervene because nature can no longer take her course. Well, she could, of course, but then there would be cries of outrage from people who came across animals that had starved to death, or where populations had grown to migration levels and the M5 was littered with maimed deer, crashed cars and orphaned children.
We already have as many as 74,000 accidents involving deer annually in the UK with the current population controls.

Anyone who drinks milk, eats eggs, wears wool or leather or who eats meat is complicit in far greater exploitation of animals, but because they are at one remove from the dirty deed, that's OK. I just wish the same level of outrage could be stoked against battery and intensive farming, but I'm willing to bet that a good number of those bleating on this thread are happy to buy their meat, milk and eggs from Tesco's, Asda and Sainsbury's, wear wool and have leather belts and shoes. If you're strict vegan, fine, but if you tuck into your eggs and bacon or stuff your face with a burger from the stall at the festival, you're really rather missing the point.
Me? I'm happy to eat the produce of my own chickens, sheep and pigs. I also shoot wild game and fish for salmon and trout and will barter venison from a stalker friend of mine. I know they've all had a decent, non-intensive existence and I can happily eat them with a clean conscience. As for the rest of you, however...
But hypocrisy always was such a quintessentially English trait.
