insecure vs. stable

The British tend to try to be viewed as having a high ego, resulting in looking arrogant to others. Why? Nathan told me that that's because they are, in fact, "insecure."

On the other hand, Americans are stable and so they relatively easily admit their mistakes when they are made--British tend to be hard-pressed to admit their faults and behave and talk like laywers and politicians, the symbol of meanness.

Such attitude of theirs is partly rooted in their long history of being an empire, wielding power over the world, and it partly proves that they are actually incompetent. They are fearful of admitting mistakes since they feel doing so could reveal their incompetence. They are fearful of losing their self-proclaimed status of king by revealing their weakness.

I think it's a meaningful point.
