Have you been on a debate team?

Nah but I made the Vice President of the high school debate team have an angry emotional breakdown during a class debate one time lol. I guess the main advice is to make them play into your narrative and control the tempo of the debate. In order to do that, question and nitpick every little point they make and doubt their validity for anything. If they say 2+2=4, say that it’s not and 3-1=2 instead, etc.
