When one enters into a discussion with a hunter on the 'merits and necessity of hunting', one is entering into a losing battle with one of their loaded guns. Not that they are right, but because their stoic feet are so planted in the blood of the dead animals they revel in destroying.
The recent slaughtering of the Yellowstone wolves despite a federal court ruling that their removal from the endangered species act was held Illegal is a perfect example of hunters justifying their 'hobby'. Even The National Park Service weighs in with facts and figures to dispute the hunters', farmers' and ranchers' claims.
Contrary to their statements that the wolf population in Yellowstone has increased, this is false if they'd check their facts. The population, in fact, has decreased since 2007 due to incidences of mange and more seriously, widespread Distemper
The real truth remains - and always will remain true - that hunters will justify any slaughter if it means they can slaughter other animals. In other words, in the case of the wolves of Yellowstone, hunters really consider them "competition". After all, any deer or elk the wolves kill for survival is one less deer or elk a hunter can mount on his wall.
Their alleged 'overpopulation of wolves contributing to the and safety and survival of the deer and elk population' is a bogus justification for wolf slaughter that smells as much as the piles of dung left by the elk and deer herds as they flee from the...uh..."sportsmen/women".
