Interesting views. Nothing I have read so far persuades me that cruelly killing or torturing an animal is justified. People who get their kicks from cruelty posing as sport will come up with all sorts of excuses and defenses, but what all of it comes down to is: they enjoy inflicting pain and suffering, so they feel nobody should ask them to stop doing it. Of course, they wouldn't think of it as "sporting" if they were on the receiving end of such cruelty.
The main issue for me is the level of pain and suffering inflicted. If an animal dies instantly as a result of being targeted by a human, that is not as bad as inflicting a painful death on it.
Bloodsports are all about making the animal suffer. Without the cruelty these "sports" would be of no interest to people who who enjoy inflicting pain on animals. It's worth bearing in mind that wild animals have nervous systems...so they experience pain as surely as domestic animals, or humans, do.
You wouldn't let a gang of thrill-seekers into your home to torture the family cat or dog. Neither, I believe, should we allow such "sportspeople" to torture or cruelly abuse animals in other situations...whether it be dogfighting, foxhunting, bull fighting, hare coursing, or any of the other ingenious sickening ways mankind has devised to make animals suffer.
