What makes a good debater?
To be a good debater, try to act confident, even if you're not, by making eye contact with your opponent and standing up straight, which can make your argument appear more believable. Also, remain calm at all times, and never shout or get angry since it will only make your argument seem weak.
How do you start a good debate?
The best way to start a debate is to open with a bold rhetorical question, a touching personal story that's relevant to your argument, or a shocking statistic. Once you have your audience's attention, define the key terms you'll be using in your debate and summarize your case.
