I do not have a problem with people eating horse meat. I would not have a problem at least trying it myself. Not to say I would like it and eat it regularly. To me my cattle are just as much loved pets as anyone's animals, no matter the species. Beef is still one of my favorite foods.
I actually was disappointed when they closed down the last horse slaughter house not too far from here. Ever since I have seen so many horses starved and left to fend for themselves because no one wants them. As sad as it is, while horses were still being slaughtered locally at least they were worth something for their meat if not for their other qualities. I would rather see a horse slaughtered than left out in a pasture with no care to die of starvation or illness because no one wanted to take care of it anymore. The horse market really fell out around here at least in the past few years. You can get a colt for $10-20 at the sale barn now. I see tons of free horses listed. Unfortunately all animals, even the pet trade is very money driven and where there is no money there is no interest. The animals are the ones who suffer for it.
