Part of the issue is that the slaughtering of horses is illegal in the United States, so I imagine it would be an issue to find that the meat was actually being served here. Sure, meat is meat, but at the same time it's the deception that's the problem. Today it's horse, but who knows what kind of animal meat is going to get slipped in next time? The "pink sludge" filler is one thing (you know they put some kind of extender in there, but it's usually some kind of grain filler), but you don't want them to start scooping up stray dogs and cats and throwing THEM in the mix...HA HA!
