not if the 20 inch penis is part of the meat butchered.

In italy is common as every other meat, and to be honest is pretty much the one that tastes better. (but that is my opinion)
So, I don't think there's something wrong eating an horse, but yeah, we all differ in culture and stuff so I can get your point.
But, still, I don't think is a thing that needs to get banner.. just keep it at a minimum to satisfy the demand.

Obviously too busy playing Super Mario

Perhaps there is reasoning for eating deer then.  What's hunting season? Killing deer for fun, like Fox hunting?

This will explain to you how hunting season works:

Depending on the kind of weapon you use, deer hunting season varies.  You can bow hunt from October to Dec 31st I believe, but gun hunting is only allowed for 9 days sometime in the beginning of November.

While some might argue it is only done for fun, part of the reason it is allowed (and regulated) is to maintain a healthy deer population.  Also, you cannot simply shoot a deer, and then just throw it away, per se.  This is referred to as want and waste I believe.  You are required to either process the deer on your own, give the deer to somebody else so they can have the meat, get it processed at a meat market, or donate it at a meat market, etc. (in other words, the final result of shooting the deer is it must be used for meat.  A lot of people will also turn their deer hides in, and in turn will receive a nice pair of working gloves).

So it is a little different.  You cannot simply go around and shoot deer just for the hell of it, as you can with small game (fox, squirrels, rabbits, etc. are considered small game).  Depending on the zone, often times you can only shoot 1 deer per person for the entire season.  There have been times where the population gets high that we have been allowed to shoot up to 5 deer per person (we shot 4 total between 3 people that year I believe).

Regardless, this wouldn't be the reason to justify eating horse, because there isn't a horse overpopulation or anything of the sort.

I'd eat a horse if i was starving to death.

oh you were talking about food! i had another image in my mind :p

I don't see the problem.

With the exception of endangered scecies, I see no relevant moral difference between eating one animal or any other.
Eating cats or dogs for example only seems cruel in those parts of the world where those animals are popular as pets, causing people to have closer emotional relationships to these species than others. But from a purely rational point of view, there is hardly any moral difference in killing chicken or horses. In fact, one might even argue that eating horses is morally better:
Because to get the same amount of meat as from killing one single horse, you'd have to kill dozens or even hundreds of chicken, so eating horses might result in less animal pain.

it takes a bit more sour than Human flesh.
