The messenger is more important than the message. People need to like you before they're willing to listen to you.
Advocating ≠ arguing. This is not a zero-sum game. It is about showing how you and the person you're speaking to can win together.
Emotions carry more weight than logic. You need to reach their heart before you reach their head.
Respect the process. You are not going to turn an Israel critic into a staunch Zionist overnight. Small steps will result in long-term gains.
Ask open-ended questions. It makes people evaluate/own their ignorance or beliefs, while showing you value what they have to say.
Listening is learning. Do it to understand, not just to rebut. Until you understand the concerns of the person you’re speaking with, you cannot address them.
Know your audience. You must determine who it is you're attempting to reach before determining your methods of doing so.
Respect the circumstances of the interaction. Time, place and other social and environmental factors influence your ability to persuade.
Seek common ground. Find broad bases of truth and agreement before focusing on the nitty-gritty.
Tell your narrative rather than tearing down someone else's. Building a positive identity around Israel is much more effective than attacking the Palestinians.
