Lias:
I realize this won't be a popular opinion, but the only part I really find objectionable is that the stabber didn't own the horse. I think vegans are daft, but unlike the vast majority of people at least they are not hypocritical about animals. Most people are happy to eat meat (well at least the meat they are socially conditioned to eat, refer uproar over the eating of cats and dogs), but I can't count the times I've seen people calling for people who hurt animals to be killed/raped/get cancer/etc. I've never had a desire to hurt animals myself, but as far as I'm concerned if you own it you can do what the heck you like with it.
You are at least right on the very first part of your post. I am not a person who attributes human characteristics to animals, nor am I particularly precious when it comes to animals for food.
I am, however, feeling sick to my stomach that you believe it's ok to torture animals even if they DO belong to you.
