Answer:
There are no benefits to any kind of horse slaughter. Americans won't eat horse meat but a lot of American horses are slaughtered for the meat market in parts of Europe. As a horse owner and lover my whole life I can't imagine how anyone could support such practices. There is another kind of horse slaughter that happens everyday in the United States. It's the slaughter of our wild mustangs by ranchers and so called sportsmem. Our own mustangs are being killed because they infringe on ranchers territories (mostly Federal land) for grazing. Others are killed for sport. These horses are a part of our heritage and should be treated with respect and dignity.
