In fairness to the communist bastard, it was fairly tounge-in-cheek. He did that because both she, and the audience, and the place he was in were all very ideologically captured. I think she responded with, "You're right, thank you". It was a very friendly crowd and everyone laughed because they thought it was very smart of him to say because it proves his loyalty to the cause.

Most people would have said many other things in response to him saying that.
