Bullfighting is a traditional sport in different places as Spain.In some places of Spain is considered a regional culture. It started probably at the Roman period. Sometimes and should be seen as an art form. Some Criticisms consider bullfighters a ritual because the bull is being killed in different manners.
Bulls are killed to be eaten by abattoirs than die in the bullring. There are many abattoirs who operate in a less than effective manner. The focus on banning bullfighting as being particularly cruel is misplaced. It is thought is a cruel sport where people killed bulls.
I think it could be considered a risky sport because the abattoirs are in danger when they are closed to the bulls.
