I have never gone hunting in my life.
And fishing is boring.
I find running through the woods like an idiot to be a far more enjoyable sport, seeing that the only thing you have the chance of killing or harming is grass, moss, leaves, etc. . .
But yeah, I guess I don't like hunting or have ever tried it because I don't want to kill anything. I'm not saying that we shouldn't hunt or anything- hell, no hunting means no meat, end of it, but I suppose I was always a bit too lazy to try it out too.
But, like Shusake said, if my dad goes hutning or something we never let the whole animal waste: Well, we usually do not get the head mounded, seeing that such a thing done constantly would most likely cost a lot of money, but you get the basic idea. We actually use the animal, so it's death isn't entirely in vain- it didn't just die to die, and serve no purpose afterwards.
As for 'trophy-hunting'.
Again, the animal serves some sort of purpose: I'm sure that although their orginal intentions was to kill the animal for a trophy, that they did something with the meat. Now, if it we're talking about a flippin' skunk here, or an owl; then no. You shouldn't kill those, especially when you are not going to eat them. Trophies are not a neccesity of life, and really if anyone dies because "They'll look nice on the wall" they might aswell not even die, because that does not even feed the predators in this case!
