Well to be honest, It's hard to be sympathetic with Americans on this one.
No the people aren't the same as their government yet what incidents occur throughout the world because of the American governments greed and lack of value of human life, will ultimately be reflected on their country. You can defend America all you like but at the end of the day, how can you defend yourself to one of those people that have been wronged by an American soldier? They are not likely to think logically if their family has just been wiped out via a bomb and so on. They will just hate America and want it dead. This pattern of prejudice is pretty prevalent through history.
People wronged in such a way aren't going to discriminate whether an American is an "upper class" American or one from a poorer area who is less educated about their government.

So in Japan they see their people being stabbed by American "representatives". It reflects badly on America because those "representatives" have been influenced by America, having grown up there and having learned the values of their country their whole life. If this type of conduct is what the Japanese are made aware of through the news or whatever, then obviously they will think there is an underlying problem with Americans and this will cause their prejudice to flourish.
I'm sure if the Japanese did the same in America, they would be stereotyped the same way.

Now as a by-stander, I can be more receptive toward the fact that there are different types of Americans and not all of them are bad. The fact is though, when threads like these are made, they are made to empathise with the party who has been wronged. If they sound biased, that is the reason why.
Bearing the burden of being branded by a particular people because of others actions is something that goes hand in hand with life. I go through the same thing when a certain crime is outlined and committed by my ethnicity, which I myself would never do. I have to bear it though, as I have been my whole life.
