How do you knock your interlocutor out of his rut?
If you don't have time to "rock out" and your opponent needs to be disqualified as a matter of urgency...or at least discouraged, I suggest the following manipulation.
You need to devalue the victim's judgment.
How do you do this?
Say to your interlocutor something along the lines of,
"Everything you said is bullshit and nonsense!" Hearing this, many people start to make excuses, get offended, or become aggressive.
What do we get?
The victim is angry or confused, and the field for manipulation and advancement of your goals is free.
