First of all, I have noticed that a lot of people do not seem to be searching for the truth in on-line discussions. They seek instead to be right. Again, this is not limited to ninjutsu or even the internet. But I notice a lot while reading many conversations. People seem to take a position and think that any attept to tell them that they are wrong is a threat to them. We can be talking about whether the ninja used straight blades, or if the ninja were oppressed minorities and you will see the same thing time after time. Someone will make a statement and defend it to the death no matter how much evidence is shown them. They will grasp at any straw, twist any argument and confuse the issue as much as they can rather than admit that they were wrong.

Second rant. I have seen a lot of abuse of the use of anologies. Anologies are good things if one person knows a lot about something and is trying to put it into terms that the other person can understand. They are not perfect, but they are a good, quick way of letting those with a lot of knowledge help those with less to come to an understanding. If we were talking about the shoen system in Japan I might briefly explain that it was close to the sharecropper system you had in America. That is not the complete truth, but you would know enough to understand when I talked about how the people tilling the land did not own it.
The problem is when those with less knowledge try to exploit and use the anology themselves. Instead of knowing something up down and backwards, they look at it rather shallowly and try to understand it in the context of something else more familiar. So if they see that the shoen system had some similarities with sharecropping, they would assume that the social stigmas about being a farmer on a shoen was the same as those that had to sharecrop in the American south. Some people even seem to want to use anologies to make a nice little reality that they are familiar with and benifits them rather than seek out the truth. People try to compare the ninja to the indians so often I want to gag. And they don't just make similarities, some of them actually think that going out and trying Indian religious practices are a part of ninjutsu training. That is only one example. If you don't really, really know the subject leave the anologies to others.
