This is actually a really common thing. In France, horses are prized for their meat.

I am obsessed with horses, and it upsets me a lot to think about the slaughtering proccess for horses, but there really is not much I can do, so I tend to block it out of my head and not think about it. If I had the power to change it, I would, but I don't.

It is their culture, there is not much you can do about it. Sorta like Koreans eating cats and dogs...
