What you write and constantly emphasize – the kilometers and lengthy texts – indicates that you don't understand what constitutes the art of oratory. Apparently, for you, understanding oratory means conveying a message in no more than 10 lines. LOL.
Any thought can be condensed, leaving only the most important points. A simple example. A thesis that is defended at an institute consists of 100+ pages (not for everyone, but for many), and it needs to be defended in 6-7 minutes. It works.
Why are some people kind, and others are not?
