lecturant
(also. Lecture-Rant, pronounced Lektcha-rant) An angry lecture that may have an accusatory undertone. A lecture-style scripted performance in which the lecturer consciously speaks truth to power and ignores codes of civility. The word was first introduced at Davidson College (North Carolina) in an event sponsored by the Middle East North Africa Student Association (MENASA).
It wasn't a lecture. It wasn't rant. It was a lecturant.
Perhaps what we need in this postmodern ineptitude is less lectures and more lecturants.
I won't be the subject of your lecturant.
(as a verb) I won't be silent as you lecturant your way out of this mess.
(as a verb) Don't lecturant me.
