The argument from about 10 years ago forward is that because English is already messed up, we should allow any usage of the language possible.
Or is this more of a federal government thing? Grammar Force as the seventh branch of the US Military? What about other countries... are we thinking NATO or UN? Either way, gonna be tough to try and convince the Brits that US English is the correct one, since we didn't exactly get permission from them in the first place.
Makes me wonder how people managed to speak English before they invented grammar rules. /s
