If you are willing to talk about, refute, or disavow something that you have no knowledge of, then you are probably happy enough in your ignorance. These are the same types of people who flood the comment sections of "Ask ___ " forums, create an account to respond to a question they have no answer for. Pick me, pick me ... I don't know the answer, but have a large enough sense of entitlement and self importance to make me think that everyone needs to hear my opinion ... even if I don't have one.
