Their whole stance is bizarre. It would be like if I believed every country should be democratic, but if any non-democratic foreigner asked me about it I said, “well I’m not going to even talk to you until you’ve read every bit of democratic theory, and even if you do, I’m not going to admit or discuss any criticism of democracy. Also, you are evil for just being born in your evil country.” They can’t possibly expect to convert anyone that way.
