  Intellectual Debate Native Speaker of English By the term, I would assume that a native speaker of English is someone who speaks English as a First Language. I guess from this definition, one can say that the Brits are native speakers of English. One would want to say that Americans would fill this description, but Americans are made up of many cultures, it's a melting pot, and it isn't homogeneous, like the English (ok, you have to ignore the effects of migration and British-Asians, or British-Africans).
Ownership This brings us to the question of ownership. I don't think a particular race/breed can claim to "own" a language. I dont' even think language is something one can own. Languages are specific to the different areas of the world, again ignoring globalization, and effects of migration.
So you have French, spoken in France and other French colonies, English spoken by the Brits, Malay spoken by those from the Malay Archipelago, Chinese in China, Punjabi spoken by the Punjabs and so on and so forth. But to assume that these people own the language is not accurate, I suppose. They are probably the pioneer speakers of the language, hence the use of the term "mother tongue" and "native speaker" but they don't "own" it per se.
