How does Ethnocentricity cause conflict?

Ethnocentricity causes conflict between two cultures when one culture doesn’t accept or help embrace the other culture. In the movie the First Australians the British saw the Aboriginals as savage and wild because they didn’t wear clothes. The British saw the Aboriginals as ‘native’, and the description of native is ‘to be born’, the British could not except the fact that some cultures are not as educated or as civilized yet. When the British came to Australia, the Aboriginals did not what to do, as they spoke different languages to the British, and the British interfered with how the Aboriginals system and way of life. Like in the book called The Rabbits, the British took over the land, and brought foreign crops, animals and diseases. This led the land to be ruined, these actions created conflict between the Aboriginals and the British in order to preserve their land. Supposing the British had arrived to colonize Australia with out disrespecting the Aboriginals beliefs and laws, and then the process may have been less barbarous and brutal on both groups.
