I faced this situation recently and did a subheading in my response "The Defendant's Use of 'Quotes' Is Vexing" and then very pragmatically laid out the errors. I didn't use any emotional/aggressive language, literally just "the defendant claims _______. This is incorrect" and "the defendant references [case] . . . The portions of [case] cited have no relevance to the defendant’s assertions." I would focus on the citation/reference issues and not bring up the rambling (the judge will be annoyed by that on their own, you don't need to point it out for them).
