In English a faggot is a type of cheap meatball or a piece of wood used for kindling (the Yanks use only one g for the second meaning I think).

There is no such language as "British" - although there are several British languages, including (Scottish) Gaelic, (Welsh) Celtic and (virtually extinct) Cornish, as well as English itself.

What most Yanks speak is a variant of English (at least for a few years until demographic change makes the USA part of Latin America - linguistically anyway). The Yanks can call their language whatever they like, except "American" as this adjective refers to a continent which is primarily Spanish and Portuguese speaking. However, they have no right to demand that we change the name of our mother tongue (Ebglish) to accommodate their lack of a widely spoken indigenous language. If the Yanks want their own native language then they should invent a new one (like the Indonesians did), re-invent an old and extinct one (like the Israelis did) or else learn to speak Navajo, Sioux or one of the other native languages that the wars of genocidal conquest didn't entirely eradicate.
