::: Sorry Alex, but you misunderstand grammar. Foreign names (whatever that means) has nothing to do with grammar whatsoever. Henry kissed the tree, Candida kissed the tree, Ishmael kissed the tree, Su Hyun kissed the tree, Dam kissed the tree all have the same grammatical structure — the particular name occurring as in the noun in the noun phrase in subject position is irrelevant. 

 ::: Furthermore, you misunderstand the article. The article is not describing any interlanguage of non-native speaker, it's rather a description of a general idealized native speaker grammar. 

 ::: Additionally, English is used by people of many different nationalities and ethnicities. And it is not restricted to one country (or whatever "this country" refers). It is, in fact, one of the most common international languages. 

 ::: Using only Anglo names can actually be considered ethnocentric. Since the article may be read by a large international audience consisting of individuals from several nationalities and ethnicities, being more inclusive for our audiences seems to be a kind thing to do. 

 ::: So I reply: stop being nationalistic and damaging your country as well as yourself. peace –
