Depending on who you are, this advice can be anything from perfect to the worst possible thing you could try to do. I'm guessing that it is perfect advice for you, and it is not bad advice for me, but I know a lot of people for whom it is bad to truly terrible.
The issue is that we have to work with the limitations that come from the people we happen to be, not the people we wish we were. If something has happened during an interview that makes you actually angry, and you stay in a stressful situation for several hours following, it is extremely likely that your anger will come out in a bad way. If this is your situation then leaving, despite being bad, is the least harmful thing that you could do.
Yes, it is convenient not to get angry. Yes, it is wonderful to keep a professional face and pleasant demeanor no matter what may have happened in the interview. But we are humans. We have human limitations. If your limitations have been exceeded, the sooner you recognize and cope with that, the less likely you are to do something you will really regret. And getting space is one of the best techniques available to us. If that means leaving the interview, so be it.
Now you may agree and immediately say that this is a personal limitation that should be fixed ASAP. I strongly disagree. I recommend reading First, Break All The Rules. We're talking about a personality trait here. In adults, trying to change your personality is usually a lost cause. For most people it is FAR more effective to find ways to structure your environment so that you play to your strengths rather than your weaknesses.
So try to keep an even keel. Avoid argument. And if, in the stress of an interview, you get angry, try to get space. If need be, ask if you can have a few minutes alone in a room to collect your thoughts. But if you can't get that, and fear you'll do something you regret, you're probably right. In that situation, exiting the interview may be your best remaining option. (But note that best does not mean good.)
