I don't care if people use it. I don't even care all that much if it's used incorrectly, because it's a pretty common thing for an average person to use a word incorrectly. But when the word means the opposite of the intended meaning, I tend to point it out, and/or break a door. Partly out of hopelesness for society. Partly because the prefix IR is right in front of the word in question.
But aside from all that, I must digress.... I hope that most- even yourself- would agree that the simple fact that a phenomenon has oozed it's way into our culture... of extremely high academic and intellectual standards... is a really bad way to judge it's acceptability or quality. Maybe I'm wrong... Maybe the masses really were right after all about Vanilla Ice, Paris Hilton and George Dubya.
We may never know.
Our business in life is not to succeed but to continue to fail in high spirits. -- Robert Louis Stevenson
