Lama Ole’s answer:
Everything I have told you about Buddhism I have said to strengthen your mind. It is not a weapon or a tool to help you win arguments or become a debate champion. When a discussion arises, it is enough to wish other people all the best while we enjoy our freedom to find happiness in our own way.
As long as people don’t try to put pressure on us or take away our freedom, we should wish them all the best and pay attention to what really interests us. But if they try to talk to us like missionaries, we should know where we stand and tell them that in a friendly way. It should happen in a calm manner and without trying to prove anything or “win” the discussion.
