He believes that the domination of English is tantamount to linguicism and linguicide, and that addressing the problem of linguistic hegemony is crucial to the development of human and cultural security.
The Diffusion of English Paradigm, which is a dominant position not only in the Anglo-American world but also in the former British colonies in Asia and Africa, is characterized by theoretical orientations such as capitalism, science and technology, modernization, monolingualism, ideological globalization and internationalization, transnationalization, Americanization, the homogenization of the world culture, and linguistic, cultural, and media imperialism.
[9]Tsuda urges international and intercultural communication scholars to recognize the hegemony of English as a subject of academic inquiry in the fields especially in the English-speaking countries.
