Complete foolishness, but every region has its own customs and games. For example, in North Africa, there is the 'sheep fight,' where they bring two rams to butt heads against each other, and the winner earns money. and some people even bet on the winner..
This is serious, even though they place a bet on them. However, things are really happening in some countries you can imagine the confident that people have on this rams. Honestly, this is quite annoying to me because I have never seen such thing in my country, although just like as you mentioned that is how it goes because we all have different ways we do things, so is quite a normal thing that we can never change.Because you dont see them in your country dont mean its a bad sports. These rams are trained rams, and they are being treated more dearly when they leave the rings. There are other annoying things people do in your country, as culture but you cant say this is annoying because it seems entertaining. At least its better than killing them rams for nothing.
