Calm down, calm down, comparing people to horses is like comparing apples to oranges.  Yes, I said they are trying to rehome as many as horses as possible.  I've been to the roundups and even brought home one very crazy mare years ago that was too much for us young girls to handle.  But which is more human?  Slowly starving to death or a quick, painless, bolt to the brain?  This is how we process our other meat animals in this country.  You don't eat meat then?  As it is now, this is the best means to manage the population, but thanks to the bleeding hearts, horses can't be processed in this country so they must be shipped thousands of miles to foreign countries.  This just adds the stress and suffering.  

There simply aren't enough homes for them and they are not for everyone.  Horses are incredibly expensive to keep, especially if they are just going to be lawn ornaments.  Once they outlive their usefulness, not everyone can or wants to keep them.  This is the reality for the horse.
