I think accusing me of lying is probably not the best way to get yourself out of a sticky spot in an argument.
You are the one pretending hunting is somehow 'natural' and fun, despite making patently incorrect claims. Horses have not hunted with man 'since the dawn of time'. They were only tamed relatively recently, and as far as we know, were still being hunted for food in the paleolithic times.
I've seen the reaction of hounds - I don't believe it's instinct at all. Have you never seen the number of hounds who don't make it as hunt dogs? Then maybe you would understand that what you think is 'instinct' is simply selection.
If you could justify why humans enjoy making sport out of killing an animal, I could at least begin to understand. But instead you make up silly stories about a made up past ... that is absurd, and not credible.
