Please explain how saying "child" if you mean child, "youngster" if you mean youngster, or "homosexual" if you mean homosexual, is supposed to be either confusing or offensive to anybody.
Anyone who's taken an intro-level communications course (generally a requirement in U.S. universities, and many high schools as well) has been taught that communication is a two-way street. I can say exactly what I mean, it's not over until the person I'm speaking to receives and de-codes that message.
Stepping away from the whole 'PC' issue, surely everyone has been in a situation, at least once in life, where they thought they were expressing themselves as clearly as possible, and yet the other person(s)
completely misunderstood what was said? It happens to everybody, and it happens even more often to people who frequently work with the public, or who are in the position of having to tell others things they might not want to hear.
Communication in
any language relies not only on the standard dictionary definitions of words, but on layers of nuance, inference and general cultural baggage that the words pick up. Anyone going from one culture to another is going to misunderstand/misinterpret things on occasion.
Someone's already pointed out the confusion that even Americans, who are (mainly) native English speakers, can feel when dealing with unfamiliar accents and colloquialisms. It's even more difficult for immigrants who aren't native speakers. Even if they speak English well, the English they speak is quite often textbook-English. It covers definitions, but not
meanings.
The reality is that, living in a multi-cultural (and yes, I'm aware that this word is likely to enrage the anti-PC crowd. See what I mean about cultural baggage?
) society, everyone who works with the public, and particularly those who do so in an official, authoritative capacity,
needs to be aware of what they're saying, how they're saying it, and how it could be (mis)interpreted. Anyone who doubts this, or thinks it's some sort of Liberal plot to destroy civilization, should pull their head out of the sand, hop in their time-machine, and head back to 1955.
