So only good people choose to own horses and they always do the right thing and never send them to auction. There aren't any people that are in it all for the money and when they can't sell the horse and make a buck off them, they NEVER send them to slaughter houses, because they chose to own the horse and they know the responsibility that comes with it.
None of those people would ever choose to slit their horse's throat, shoot them in the face with shot guns, light them on fire, stab them till they die, shoot them with nail guns, wrap metal wire around their throat till they can't breathe, or any other horrid death they can think of when they don't want the horse anymore. They don't bother to drive the horses to auction because it costs them more gas money than they would make in "meat" money. And you are probably so naive to think I'm making all those things up.
