You are not in danger of going without meat or protein. We have plenty of farm animals that we've specifically raised for this purpose.
What's more, our technology has greatly outpaced evolution. No quarry has a chance against a decent marksman; they don't understand how a little moving blob on a hill a quarter of a mile away could possibly be dangerous. I do hold a begrudging admiration of people who hunt using more primitive techniques (such as atlatls). At least then, the quarry had a chance.
So you have no problem with someone else killing a penned up animal that had little chance just to feed you, yet you begrudge someone that wants to do it themselves? You do realize that farm animals have to die to give you that protein?
Your comments on technology and evolution seem to indicate a great deal of ignorance as to what hunting really is. Have you ever hunted? In regards to the hunting I have done, it is not as easy as you describe. For one thing, I am not much of a danger to a deer a quarter mile away because I doubt I could consistently hit a target that far. Despite all our wonderful technology, the animals I have hunted have great senses and will avoid me if they can hear me, see me, or smell me.
This is the same ad hominem nonsense that anti's use against us along the lines of, "If you own a gun, you're obviously a fat, drunken redneck with undersized genitals who only wants to have the opportunity to shoot other people who break into your house."
As for ad hominem, you throw out a few with your equating of controlling the population af an animal with going in to famine regions and killing people. While I respect animals, I do not think they are the same as people, which you clearly do.
