I had a couple interviews when I was young and callow and really needed the job that still stick with me. One was with a large company that's still around. The HR manager accused me of lying on my resume after I interpreted something like "where are the stretchers, c'mon, everybody exaggerates on their resume?" as "discuss the limits of what you claim on your resume". I learned later this line of questioning is promoted in some books as a "trick" for getting people to admit they lied on their resume. I was pretty rough around the edges back then, so I was rude back, which I regret.

I am now a hiring manager and have conducted countless interviews at this point.

You did the right thing continuing the interview professionally. Assume the most charitable interpretation. You don't know the whole situation with the jerk. Maybe he just started and this is the start of a chain of problems that will get him fired. Maybe he just needs training on how to interview. Maybe he's OK otherwise but they'll never let him interview anyone else again. Maybe he's only sort of a jerk normally but he was leaving for a funeral or something.

There's just no good reason to get yourself a "not now, not ever" note in the company's files and your interviewers' memories just to indulge a bit of social revenge. That said, use your best judgment and certainly remove yourself from an interview for illegal, dangerous, unethical, or threatening behavior. The crazies are out there.
