I liked Zinns way of asking what if we reverse the question and ask "What if we could end WWII right this moment, today, but to do it, we would have to kill 100,000 American children." Why are japanese ok to kill but, Americans are somehow deserving of life?
In that particular case the Japanese brought it onto themselves. Their conduct showed few morals and quite frankly it was a good call given the information available at the time.
Not to mention that the invasion of the mainland wasn't necessary, Japan was pretty much defeated before the first bomb dropped.
Japan was defeated but they refused an unconditional surrender. Everything at the time indicated that they would fight to the last man. What are you supposed to do?
Humans have a very difficult life, as well. You have to work for money, and sometimes there's no jobs available. There might not even be food available in some areas or countries! Maybe not even water. Would I prefer to be fed? Yes. Would I prefer to be fed if I'd just be slaughtered later? No.
That's fine, but are you sure others share your opinion? Do you think you would manage to keep that opinion while starving? What about those in the 3rd world who take jobs they know are going to kill them through poisons / poor safety etc. just so they can survive / feed their family etc. If they took that option would it not be too far to argue that faced with what I outlined they would take that choice? After all, desperation has driven people to do all sorts of things.
Would you want to be raised on a farm for the sole purpose of being slaughtered later? Or is that not okay just because we're humans?
My key point (whether you think its valid or not) is that this is not a choice in isolation, it is an alternative to what would be conceivably be their "normal life". What I am saying is that animals face such desperate conditions in their normal life that it might actually make this choice the more "moral" choice of the two.
Living for a brief period before you're slaughtered sounds better than being free and living a normal life? I don't even want to know what your views on what actions the government should take are.
You are ignoring the very real fact that living a "free and normal life" for animals is almost constant suffering. Unless you are a apex predator life is very scary, even if you are, you are cold in the winter, constantly hungry and you best hope you dont get sick or injured as its all over in a very nasty way.
The life they have on farms etc, it a lot better than this and the death they get at the end is better than almost any way you can die in the wild. Its nice and all to talk about "freedom and a normal life" but are you sure that is what they would want?
Never ask two questions in a business letter. The reply will discuss the one you are least interested, and say nothing about the other.
