Well, what else are racehorses bred for ? OK, racehorses are not ceremonially killed in front of people to provide a spectacle, but ultimately their EXISTANCE is for our "fun", is it not ? Similarly greyhounds. Once they are past their usefulness as a racer, very few of them end up retiring to a loving family to live out the rest of their days. Yet I don't see the widespread condemnation for horseracing / greyhound racing as we do for bullfighting. And the only reason for that, really, is because we don't actually see the horse or greyhound being killed in the end.
Ultimately, it all amounts to the same thing though, dunnit ?
No. Because, again, the issue (with fox hunting, and bullfighting) is that people are ENJOYING WATCHING THEM DIE. That's the ONLY thing I (and I think a fair few people) have an issue with. Regardless of whatever happens prior to that during the animal's life.
