Colonization and The First Australians-Hisham

How did the ethnocentricity of the British and the First Australians cause conflict between the two groups?

The British were quite full of themselves and they "knew" that they were better than the Aboriginals without even confronting them. This eventually caused conflict because the British had kidnapped Bennelong, just to teach him the right way to live. After this, the British expected them to be welcome by the natives, yet they were not. One member of the Aboriginal tribe, Pemulwuy, had thought that this was a very rude act that had been committed by the British, and so he speared McIntyre. After this, the British knew that the relationships between the two groups was not very close and safe. The Australians however did not think high of themselves, and they decided to start a war, and they did, but lost. A man the British called Saturday had to come out and declare peace, and surrender to the British.
