It's interesting how many people don't get why stallions are gelded--aside from the issue of the reproduction of horses that most likely will end up in the slaughterhouses. If gelding does not occur, most of the stallions will never be able to be around other horses without issues. Then, what happens to the stallions? Death. It's like cats and dogs.....if they roam intact, we get millions of them reproducing and then what? Their nature is to reproduce............
