new cultures?

Growin up as a third culture child I found myself being understanding to other cultures. But I did not know if I was truly becoming somone who was able to become a part of the culture. I was purly akward. One road always crosses another, and in the crossing there is bound to be a accident. one by one we tend to think of ourselves as the upper hand being the "better" one. Some even think to the extent of saying "We need to help other countries, they do notknow how to live a civilized life" What is "help" in that sense? Are we suppose to truly give them what they want or are we force them for their own good. Currently many cultures have been destroyed due to the fact that we are introducing new methods of a "better" life. We are slowly destroying the cultures that actually are keeping this wordl in shape.
One way to stop this injustice is to be understanding. Just like any relationship, especially one with an opposite gender the cultures must be delecate with eachother. Because counries contain different cultures the people also contain different cultures. If people simply think of the culture as another family the simplicity of not destroying cultures may occur. And that is what respect and honor is.
