Pakis out is a term used by narrow minded, ignorant, racist individuals. Usually in the UK, and usually white, though it is known that some black people use the phrase aswell. The media class it as a ethnic tensions amongst working classes, though a proportion middle class people in predominately white, suburban areas agree with said phrase... Thanks to the Daily Mail
Violence against whites and black by asians (Muslim, Hindu, Sikh) is usually a product of the harrasment, persecution and marginalising of the group in the area, and if not, then self defence! If there is no harsh and discriminating attitude to an asian person then one will likely recieve no hostility.
