What I've found with a few discussions I've had lately is this self-satisfaction that people express with their proffessed open mindedness. In realty it ammounts to wilful ignorance and intellectual cowardice as they are choosing to not form any sort of opinion on a particular topic. Basically "I don't know and I'm not going to look at any evidence because I'm quite happy on this fence."
The Net is best considered analogous to communication with disincarnate intelligences. As any neophyte would tell you. Do not invoke that which you have no facility to banish.
