Well, I found one complete answer that coincides exactly with my understanding of the word What is a comment?

Now it is rare that I make comments on any of my Blog posts, but yes there are ‘odd’ cases. Recently on this Blog I attempted to make a ‘comment’. What I was confronted with when I first clicked on the ‘comment’ box at the bottom of the post was indeed a surprise, some mindless waffle regarding typing ‘/’ to choose a ‘block’.
This is what you get when you attempt to ‘leave a reply’..

So wordpress apparently expect readers of my posts to understand this rubbish?
The so-called ‘Gutenburg’ block editor is defaulted throughout the editing interface of wordpress.
There have been suggestions online regarding the ‘editor’, none fulfil the task required – removal of this all-pervading nonsense from a ‘normal’ editing environment.
My intention is to ‘use up’ my current subscription, and then cancel wordpress.
Get this LOUD and CLEAR wordpress. I’ve written in HTML for many years, I’m NOT REMOTELY INTERESTED IN USING THE ABOMINATION ‘Gutenbug’ editor. NOR, foist this on commenters to my posts.
