You're reading a lot into what I've said (e.g. hearing that some versions of English that are in use can be invalid). One way to tell that I'm not invalidating any particular version is that I put "ungrammatical" in quotes. Whether we like it or not, when non-natives from 5 different countries get together in a room in Petropavlovsk-Kamchatka, the subset of English they're speaking is largely the same as when non-natives from 5 other different countries get together in a room in Lima or in Gaborone. The language they're speaking has grammar rules. It can be thought of as "standard Global English" because it's identifiable, distributed, and distinguishable from American English, British English, Singlish, etc.
