You're welcome, Terry, and thank you for your post.
Through the work of editing a courtroom thriller, my client gave me THE BEDFORD BIBLIOGRAPHY for TEACHERS OF WRITING, Fourth Edition, by Patricia Bizzell and Bruce Herzberg.
Likewise, I was gobsmacked that there is so much more underlying the theory and practice of writing. Similar to your entries, there is concern not to hurt the feelings of "basic writers," et al.
My already overloaded brain is in overwhelm mode . . .
