This is a hard question as I like most sports! Many people have reservations about sports like bullfighting, cockfighting and dogfighting for ethical reasons. Some have reported Bulls who are used in bullfighting are deliberately weakened before the fights by being drugged and sometimes having their horns shaved down in order to disorient them, sandbags dropped on their backs, and petroleum jelly rubbed into their eyes to blur their vision.If this is the case, this isn’t very fair on the animal!
Depends on what you mean! There’s certainly a lot of sports which involve animals that people object to on ethical grounds, like bullfighting, hunting, etc. There’s a lot of peculiar sports which involve putting your body on the line, but maybe the worst ones are where lots of people play but the risk of injury is great, like american football or rugby. I think a sport should be fun, and good exercise, but it’d be nice to be able to walk when you’re 50 after a lifetime of playing it!
