What I find misleading is the title of the thread...why ask a question when you have already decided on an answer and aren't prepared to accept other theories or beliefs?
To me that is the essence of an unrealistic outlook. I often find people that ask these rhetorical questions do so to espouse their own beliefs and I've seen this type of behavior used in cults. They give you an answer before you've even answered. If so, please don't ask questions that you don't wish to see answers to that you don't want to read.
