During the open forum at the University of Pennsylvania Ravi Zacharias and Nabeel Qureshi were asked:
"Why are you so afraid of subjective moral reasoning? Do you think we all are just going to start raping and pillaging just because we don't have a book telling us what to do? Are you afraid of that? I'm not because that's not what we are going to do. Yes, Nazis were bad but there were Christian Nazis and atheist Nazis. So I don't see... What are you so afraid of?"
To this Ravi quickly replied, "Do you lock your doors at night?" Watch his full response in the video above.
