Despite my rhetoric, I'd bet I agree with you more than I've made it sound. ie, I know the difference between professional and unprofessional communication, and agree that professional communication inherently sounds better, and it's what people would strive for. A less extreme version of my argument might be that although it's important to help coach people to communicate effectively, but it's also important for managers and executives to understand the value of an idea even if someone is less able to speak professionally.

Also, plenty of communication works better via text. For example, a book has a very different format than a speech, precisely because of the strengths of the two formats. The same is true of something like a small talk vs. a technical document. And people, with their reliance on body language of course benefit from books and technical papers quite often.

Anyhow, this is a sore point of mine, and I seldom see much agreement on my position. So, thank you very much for your polite discourse on the topic.
