Q, who is penalizing anyone? If you happen to ask me (who learned his first English word at the age of 10), use your dialect whenever adequate. I wrote about noncolloquial contexts, i.e. not colloquial.

BTW, to all of you: The postponed preposition, preposterous so-to-speak, has been taught to me as a peculiarity of English language. Certainly there is no logical argument forbidding it. Which authoritative source declares it wrong?
