Ethnocentrism
From lurkmore wiki
Ethnocentrism is the judging of another culture solely by the values and standards of one's own culture, and can be best described as the kind of racism that most people are ignorant of and unconditionally act on, especially on the internet. It can, in short, be best described as a hypocrite's racism, as most of the time, it is done out of elite and smug attitudes with a sense of impunity and ass in head ignorance.
