First, the deer population is VERY out of control. That is a fact proven time and time again. There are FAR more deer in this country now than there have EVER been. They are indeed starving, ruining crops, being killed by cars, etc. Not to mention causing human deaths in vehicle/deer accidents as well.

Second, IMO, if one eats meat of any sort, one has NO room whatsoever to criticize hunters. I personally don't hunt, BTW. If you had a hamburger for lunch, someone killed a cow on your behalf. Or a chicken, turkey, fish, etc. Just because you didn't personally pull the trigger, the animal died to feed you nonetheless. There is NO difference in a deer dying to feed someone than a cow dying to feed someone. And, actually, at least the deer theoretically had a good, free life for some time before it died. Domestic food animals do not.

As far as deer head mounted on the wall, I personally think it's ugly and tacky. But, if you kill the animal, why not use all of it you can? If you like that style, I see nothing really wrong with the deer head ending up on the wall as opposed to ending up in the landfill.

The caveat is, of course, that the deer is actually eaten. I do NOT condone "trophy hunting" in any way. Killing just to kill is wrong, no matter what is killed. But killing to eat is the natural way of the omnivore, carnivore, predator.
