This raises a very good question, what exactly is a "morally neutral stance" and does such a thing actually exist? I must admit that I'm often guilty of taking a stance on something without actually understanding what it is that it's referring to, and this may be one of those instances.
So to understand my position on a "morally neutral stance" let me first explain what I think it's not. Some might consider that most animals have a morally neutral stance because they act without regard to that action's moral implications. But they do this simply because they lack a concept of good and evil which is indispensable to making such judgments. Therefore they're not morally neutral they're simply morally oblivious.
Likewise people are often morally oblivious as well when they act without fully understanding the implications of what they're doing. But in such cases we're not morally neutral, we're simply morally oblivious. In our ignorance we humans are often guilty, not only of being morally oblivious, but through our ignorance, of actually doing things which are morally wrong.
On the other hand let's consider two countries which are engaged in a dispute for some reason or other, with skirmishes and conflicts stretching back generations. Each side will likely claim the moral high ground, and point to history to justify their claim. In such a case an outside observer may well take a stance that's morally neutral, understanding that both the action being taken and the events that precipitated it are equally unjust. We as a species have long recognized that certain acts, although fundamentally immoral, are none the less justified if they are undertaken for a just cause. Which can inevitably lead us to taking a position that's morally neutral.
In other words these are actions, such as killing others, that we would never claim to be morally right, but we would accept as being morally justified.
Now I'm very open to differing opinions on this. So please give it some thought and let me know what you think.
