Walkergal, do you actually think there are "people" who can buy horses to save them? Where do you live? The local papers, craigslist, classifieds, are full of horses to give away because someone can no longer feed them, the choice is their family or the horse. Its' sad, but when the choice comes to pay the rent and feed the family and feed the horse, then something has to go. Hay is expensive, alot of folks can no longer pay for feed. I will assume you have never had to deal with reality, watch someone in the family lose their job and be glad to work at McDonalds to keep their family in a home. Sure, they had a good job and keeping a horse was easy, now it isn't. So, they have to sell the horse for slaughter, people are no longer taking free horses, rescues are full up, retirement farms are full up. Where do you want these horses to go?
You need to face reality. Don't say "I know what I am talking about" because you obviously don't. I would rather see a horse euthanized or destroyed for slaughter instead of being turned loose on public land to fend for itself. Ever see that happen? A horse that is used to being fed twice daily now have to live in a desert with no grazing or water? Do you think that horse would rather starve to death or be put down quick and painless? People are taking horses onto public land and turning them loose to die a slow painful death because they are not wild and can't fend for themselves. The wolves, bears and other critters are now killing and eating them.
So, maybe you better really think about what you are saying. Unless you are a PETA, HSUS or other fanatic, then horse slaughter is not abuse, it is saving an animal from a slow lingering death by starvation or dehydration.Only the PETA, HSUS, etc folks make it sound horrific, of course their desire is nobody owns ANY animals at all, ever.
