I guess some sports are ok, in fact many. But some I don't like.
Boxing: How can it be in this day and age in supposedly civilised countries, that two men can be allowed punch each other in the body and the face until one of them becomes uncouncious or they go to the end of the time periods and a score is given. Many minutes of sustained beating received by both parties. What fun.
Fox hunting: Such pleasure derived from dogs ripping foxes apart. Nah, not to my taste.
Cock fighting: Well, there is the one that comes immediately to my mind, but I am talking about the version that happens in western countries by Asian born people where fowl rip each other apart. A truly wonderous spectator sport.
Rodeos: Oh, aren't they great. Frightened animals in pain trying to chuck a rider off. Marvellous.
Bullfighting: I would love to go to Spain. But they think it is fun to inflict pain on bulls and have them slowly bleed to death. Actually, is there is a connection to the way they have sex? Quick, fast and furious. Don't care if it hurts. (stereotypical, I know)
What do all the above have in common? Humans inflicting pain on other animals, including humans. Aren't we wonderful?
