I beg to differ. It is one thing being creative in the use of the English language. It is another when the perception of being creative stems from wrongful use, as is the case among the youth of today in SG. When you are proficient in the language, by all means go and be creative about your usage (that's how we have poetry, literature, metaphors, personification etc). Telling kids what you just said will only give them the misleading impression that it is perfectly okay to not master fundamentals such as grammar and vocab.
Personally, I would actually advocate Queen's English, being the purist that I am. :p
And I wager Picasso's Cubism art works would have been labeled as bizarre and ugly by many art 'purists' at the start of the movement. Of course, the same art 'purists' now rank Cubism art pieces with Renoir's Impressionist works at the very top.
Creativity comes from daring to experiment with all forms, not just what you think will be socially acceptable. For example, the uniquely Singaporean phrase of "Bang balls, man!" in one lovely, succint phrase, encapsulates what Queen's English would need to accomplish in quite a few words, "This is so frustrating, and I will have to put up with it."
How many times did Shakespeare wrote spasm-inducing sentences, breaking all rules and structure, before he came up with the lovely prose he is famous for now? What about the line in the Merchant of Venice "between you and I"? Between you and I, that is the correct grammar, and "Between you and me" is the wrong grammar. Between you and I, I refer you to this NY Times
post from way back in 1988, that was required reading given to us by our lecturer.
I am not saying we should encourage kids to continue - we should enlighten them on the correct usage of English, but not FORCE all the pronouns, adjectives, verbs, adverbs, enunciations, etc etc into their throats, and slap them silly when they do things differently.
Most importantly, what is not acceptable now, very well could be acceptable a few decades later. What is acceptable now, very well could be plain outright bizarre a few decades later too. For example, I said "That's totally lame." to the young daughter of a friend, who promptly looked me up and down a few times as if I am a weirdo, and said "It's called lay-moh now, uncle Kelvin."
I grinned, and said "Ah yes, I stand corrected. That's totally
lay-moh."
It is now part of my everyday vernacular, and my friends are picking it up fast, because it's so catchy. You, dear sir, are
lay-moh.
P.S Do you realize that your opening phrase "I beg to differ.", while being standard Queen's English, is very weird when you look closely at it? Why do you beg? Why not just say "I see things differently." or "I have a different point of view." Are you accepting me as your overlord? Or are you truly a beggar in profession? Do you hold your paws together? And have you given me a chance to say "No, I'm not accepting your beg." If you look at it even closer, is it grammatically sound? Shouldn't it be "I am begging to differ."? What is English, if not clay to be molded in the hands of children, so all kinds of delight can come out of it?
P.P.S Some enlightened circles recognize the term "purist", when someone uses it, as the same as saying "I am an inflexible a-hole who have nothing better to do in life but to gripe about things I am unfamiliar with."
