I was just trying to get a number of key points across calmly and succinctly without wasting time diving into a long-winded academic debate about whether or not I am "allowed" to use a programming language that I have used with success for the last decade!

Not sure that I have any tips for you. Other than that it is often helpful to remove unnecessary words when communicating. This is something I have become sensitive to over the years. I used to write a lot more voluminously but I find it is harder to convey messages to people when they are confronted with a wall of text.
