is this whats happening to tamils abroad?

following excerpt is from Frantz Fanon's The Wretched of the Earth:

"where individuals are concerned, a positive negation of common sense is evident. while the settler or the policeman has the right the live-long day to strike the native, to insult him and make him crawl to them, you will see the native reaching for his knife at the slightest hostile or aggressive glance cast on him by another native; for the last resort of the native is to defence his personality vis-á-vis his brother."

to me it seems like this is also true in the case of immigrants. How many tamil on tamil fights have we seen? why is it always tamil fighting other tamils? Tamils rarely fight people of other races but if its another tamil they won't resist fighting.
