David,
The basic content of your comments is absolutely fine. However, you appear to assume that I teach maths. This is absolutely incorrect. The last time I did any teaching was as a graduate teaching assistant twenty years ago.
Furthermore, your tone is once again inappropriate. For example, it would be better to say "Your experience" than "Your erm, experience". If you're wondering why no one else is pointing this out, the answer is not that no one agrees me with that you're behaving obnoxiously. The answer is that people are giving you a great deal of licence because they value your professional expertise. Whether you should take advantage of this licence to abuse people is up to you.
