Unfortunately, racism, xenophobia and antisemitism are still widespread in a lot of countries.
But can people from different origins and cultures live peacefully together in the same country?
Racism appeared for a long time ago. First with slavery of black people. After black people do not stop to be persecuted with the segregation in America or the apartheid in South Africa. Moreover every know the anti-semitism of nazi and its consequences. However, now a lot of law exist to fight against the racism and to live as equals in the eyes of all, and to live in the society without taking into account skin color or religion. However some countries denied these laws.
To summarize people from different origins and cultures can live in the same country if the country's law punishes racist acts.
