How does Ethnocentricity cause Conflict?

During the majority of the British colonization of Australia, relationships between the Aboriginal Australians, and the English settlers were not too great, mostly due to the ethnocentric views the colonizers had of the natives. It was because of their ethnocentricity that many aboriginals and settlers were killed. Many innocent lives taken because of the British's incapability of accepting those that were different than them. The British viewed the aboriginals as animalistic, barbarous, and savage. They were very different then the British and this was not something that the colonizers were ready to accept. On one occasion, the British came across many aboriginal crops. This food was very different from their own, so they decided to take out all of these crops and replace them with ones that they liked to eat, such as corn. This created a conflict between the natives and the settlers. The Aboriginals didn't like that the British were taking liberties with their land, and thought this action unjust. However, the British viewed the natives as animals, who couldn't own any land. Another example of the ethnocentricity of the British was when they decided to 'help' the half-caste children. The British took away children of half-native and half-white ethnicity and put them into a boot camp in hopes that they would breed with white men and produce white offsprings. They tried to turn the half-caste children into "pure-bloods." It was unfortunate, in the eyes of the British settlers (who were now referred to as Australians), to be of Aboriginal decent, and they believed that it was their obligation to help those who were doomed to have been. This aroused yet another conflict with the Aboriginals. It was their belief that the British/Australians were stealing their children, which, from a neutral point of view, they were. Had the Australians have been more accepting of different cultures and minor differences, they could have had a great harmonious relationship with the Aboriginals.
