Explaination: What is nationalism you may ask. Nationalism is sentiment of a political nature that ignites xenophobic and racist prejudices in the minds of an ethnic group within a nation state that incites such a group to band together to conform a representative majority that could advance their espoused and unjustified beliefs regarding the superiority of their ethnicity and neglect or destroy (sometimes even as far as kill) any other form of political representation in order to, eventually, form am ethnically homogenous nation cleansed of any form of diversity.
