let me start off with a scenario.
your taking a walk in the woods one day and you stumble upon a very angry animal(dog, pig, bear, whatever) that proceeds to charge or harras you. your in a pair of jeans a t-shirt and jacket, the only protection you have is a small .22 caliber pistol in your coat. how many shots from that pistol do you think it would take to drive away or kill that animal?
If you manage to stumble across a very angry animal, chances are it is you, the human, that has screwed up. If this happens, you apparently will have been in condition white, stumbling blindly through the woods with no real situational awareness. From a wildlife standpoint, that puts your behavior into the prey category.
Think about it. If you stumble across an angry animal, it was angry before you got there. It will undoubtedly be making noises that you should have noticed and quite likely will have been in motion as well. Such an animal should be no surprise to you.
Maybe it wasn't angry before you encountered it, but is now? Quite likely, the animal will interpret your quiet approach as that of an aggressor and the animal may react by trying to defend itself against you.
If you do get attacked, it is because you have failed in your understanding of the situation of being in the woods. As a human, you are soft underbelly all over for the most part. You are a very easy prey animal with few natural defenses. You aren't fast. You don't have big claws. You don't have big teeth. You don't have thick skin or heavy fur. Such pitiful animals are best protected in a herd type of situation where their individual chances of being picked off are slim, but you are traveling alone.
If you are going to be traveling through the woods alone, possessing poor situational awareness, with only light clothing and a .22 for protection, don't count on coming out of the situaiton in good shape. If you are already making that many significant mistakes when you are out in the wild, then you will likely react wrongly when you encounter the animal and probably do many of the behaviors that will help signify you as prey, like running, screaming like a little girl or injured animal).
