Your mother has a right to be racist in her own people's nation. Minorities in Australia who are non-white commit a disproportional amount of crime even though they are so small population wise. They bring crime and drugs to neighborhoods and no wonder so many Australians are racist as a result. Racism is healthy and natural, it is human nature. Scientist found that babies are racist themselves and is a evolutionairy trait: http://time.com/67092/baby-racists-survival-strategy/
A Nobel Prizing Winning Scientist, James Watson, who was the co-discoverer of the structure of DNA has said that not all races are equal(that some are more intelligent than others), and to think otherwise is a delusion. He said to think all races evolved the same, despite being in different environments is an illusion: http://www.independent.co.uk/news/science/fury-at-dna-pioneers-theory-africans-are-less-intelligent-than-westerners-394898.html
You are brainwashed, you are indoctrinated in school because the people with your kind of beliefs have infiltrated your educational system. Your ideas are wrong, and which is why 3 world leaders condemned multiculturalism as a failure, which were David Cameron, Prime Minister of the UK, Angela Merkel, Chancellor of Germany, and Nicolas Sarkozy, the recent former president of France.
To find the links of these world leaders saying such a thing look below. Your mother isn't has brainwashed and indoctrinated as you because she grew up in a time when most of the educational system wasn't taken over by tyrants who inject their political beliefs and ideology into school textbooks.
Your people are your family. They look like you because you share the same flesh and blood. Your mother loves you because you share the same flesh and blood as her, and look similar to her. That is what a family is, and why they love each other because they share a strong connection and see themselves in each other. You share distant fathers and mothers with your own people, even if it was a 1000 years ago you still share the same ancestors who look like you. You are being racist and xenophobic to make a distinction between your mother or father and some strangers, family is just a social contract right according to your beliefs?
