Apparently, Qanons are calling her "Roberta Paulsen" after the character "Robert Paulsen" in the movie Fight Club. He get shot in the throat. (I never saw the movie, this is just what I learned.)
The Robert Paulsen character is played by the actor/singer Meat Loaf.
They then tied this back to Ivanka's tweet (on Jan. 5) of a picture of POTUS eating dinner and tagged it "#meatloaf," which got the entertainment press all in a tizzy because she "must have made a mistake." She replied that meat loaf is what he had ordered for dinner.
So they are connecting the # to the incident/shooting at the Capitol by calling Babbitt "Roberta Paulsen."
Clear as mud?
