If you had to ask me which 2 places have the most racists in the world I would say Hong Kong and Australia.
Hong Kong has the exports for almost everything, it had once been controlled by the British. This place is very interracial, it even has many foreign maids, from places; India, Philipines.
Races in the whole of Hong Kong include; Koreans, Canadians, Americans, English, Japanese, Indaisn, Nepalese and Vietnamese.
I have heard stories about HongKongers being racist to the other HongKongers who live in different suburbs or provinces;Kowloon and New Territories.
Australia is also a very interracial place, since the immigration rule came out in the 1800s , there has been a lot of migration coming in from parts of Europe and Asia.
Common races you see in Australia; Vietnamese, Wogs(Europeans) mostly Italians, Greeks, Chinese, Indians, British, South African and New Zealanders.
I have personally encountered with a lot of racists too in Australia.
The Wogs used to be teased by the Aussies in the early generations while now the wogs group together and has a tight relationship with their cousins and family relatives.
