You should look up the facts and not just regurgitate what the HSUS and animal right groups have made up.
The AAEP and AVMA have been and always were opposed to double deckers hauling horses. They endorsed the legislation that limited the time horses could spend on the road and endorsed NOT using double deck trucks. The Federal Government was the last to stop using these trucks. They routinely hired them to haul mustangs from Nevada to Oklahoma (non-stop) until the legislation passed, even after the mustang handlers near me at Pauls Valley petitioned them to put the mustangs on floor trucks.
The American people have always been against humane slaughter of horses. The problem is, they are mostly city people know nothing about it or about the unintended consequences of stopping slaughter in the US. They live in the world of butterflies and roses where every horse should be able to live out its life in nice green pastures with plenty to eat, good Vet and Farrier care and everything it could possibly need until it dies hppily of old age.
The reality is that there are hundred of thousands of unwanted horses in the US. They are not all the product of over-breeding or bad owners. They are the product of supply and demand that is constantly changing, the 'left-overs' that do not train well, have horrid conformation, bad dispositions, injuries and are not suitable for what they were raised for. They are old broodmares, unsound saddle horses and thousands of other that fell through the cracks. They are the products of a changing and worsening economy.
All that aside, all I want everyone to do that is so against slaughter to tell me exactly what YOU WANT TO DO with the hundreds of thousands of unwanted horses that are out there TODAY. The have already been bred and raised, many are untrained and nobody wants them. When taken to an auction, no one will bid on them and they cannot be given away. [Most owners have tried unsuccessfully to give them away.] The owners cannot keep feeding them and there is no place for them to go where they would receive adequate feed and care. What do you propose to do with them today?
It is not greed that motivates most horse people to be 'pro slaughter'. It is that we live in the real world and see way too often how these unwanted horses are cared for and how they die. We think it would be FAR better to have regulated slaughter here in the US where it can be controlled and monitored than to ship these horses 1500 or more miles to an uncertain death or let them starve to death in some back pasture. Do you want the next truckload that ships from our local auction to be shipped to your house? I'll bet it can be arranged! I'll also bet that I have 'saved' or 'rescued' if you want to call it that [I don't] more horses than you have even owned. I own and am using several horses right now that I bought at the local auction and the only other bid beside mine was the killer buyer.
I am waiting for your answer -- not holding my breath -- but waiting. Until you have an actual better solution, you should work toward local slaughter facilities all across the US. It would be a lot better for the horses than trying to stop the only method there is to eliminate hundred of thousands of unwanted horses without starvation and neglect.
