I'm certain that if many of the 'anti-slaughter' people where raised a different culture, they would eat horse meat just the same as any other :) In some cultures, cows are holy and cannot be eaten, just as in our culture, horses are an important figure and eating them is just out of the question for the average person.
A big problem, in my opinion, is the captive-bolt gun slaughter method. Animals do kick and move, even though they are completely and utterly dead in the captive-bolt gun method. To a lot of people, this gives the impression the the animal is still alive when it's really not. The kicking and movement is just muscle spasms, the last of the bodies electrical impulses. The brain itself is pretty much mush. All the important stuff, the areas that make us think/feel/breath/etc. are destroyed and whats left behind has about as much feeling as a lump of coal, to be honest about it.
I completely agree with kevinshorses's post. These horses live a pretty much natural life then one day, poof! Lights out before they know what even knew what happened.
Honestly, I think people should instead of advocating for NO-SLAUGHTER-OF-ANYTHING-WHAT-SO-EVER-BECAUSE-THEY-HAVE-FEELINGS-TOO!. Should advocate for THE BETTER TREATMENT OF SLAUGHTER ANIMALS. Think of cattle feed lots, pig farms, chicken farms. These animals are crammed into a utterly unnatural lifestyle for the sake of profit. It's not that they are raised to be eaten that is wrong, it's the way they are raised to be eaten that is wrong.
I'm not saying that every cow should have an acre of lush pasture to roam, or that every pig should have is personal mud puddle to roll in. But the way that these animals are literally crammed into what is already the bare minimum space is wrong. Cut a few dollars out of the yearly profit by cutting back on the amount of animals per square foot. You end up with less disease, mental problems (that can lead to human or other animal injury), and better meat.
I'm honestly not offended that people raise horses for human consumption-granted, these horses better be well cared for.
I breed, raise, slaughter, and butcher my own rabbits for dinner. My stock is given ample space, fresh water 24/7, and good food. They are kept in a heated and cooled shed. During the summer I take the time out of my day to let the romp in the yard and graze in predator-safe pens, which encourages good mental health. They are killed instantly and humanely. The result is delicious, fresh, quality meat.
At the same time I have a pet bunny named Bananas. Banana's has an adorable personality, loves to cuddle and was hand raised. The difference between Banana's and the other rabbits is that Banana's is a pet, the others are livestock. Same breed, same species, same everything. I couldn't kill Banana's if my life depended on it, but at the same time I will happily eat her sire with a side of mashed potatoes.
I would rather amputate my foot than eat Loki, but if you gave me a young horse and told me to turn it into steaks, I would. Theres a MASSIVE difference between a companion and pet and livestock. A companion brings me joy but an empty stomach, livestock bring me a full stomach and no emotional gain.
My ancestors ran in the Evolutionary Race. Horses, cows, pigs, goats, rabbits, sheep, chickens, ducks, geese, and many others lost that race.
Big fish eat little fish. Huzzah.
Wait! I'll fix it....
