I dunno. Seems like horses are different from cattle. Cows are way stupid, like meat lockers on hooves.
I'd eat Ole Flash if there was nothing else to eat, but I sure wouldn't support ranching horses for consumption. Just has en "ewww" value to it that I couldn't/wouldn't want to learn to shake.
I agree, with all the delicious brain dead animals out there, why start in on the smart ones? Id try a bite out of curiosity, but can't see making a practice of it.
Pigs, OTOH, are thought to be smarter than horses and even dogs.
But most Americans have no problem with pork on the menu.
