As it stands right now, I wouldn't eat horse meat because of my own personal squeamishes. I would, however, sponsor a program that slaughtered unwanted and neglected horses and sent them to starving children, if such a program existed. It takes care of two majorly depressing issues: Animal cruelty and human starvation.
Now, lemme just tell you, if the apocalypse hits and there is no meat to be found... you can bet your booty that Dixie the Fatty out there in my pasture better plan her escape, because she'll be feeding us. It would take the apocalypse for me to eat a horse, but if the apocalypse happened, I'd do it.
