Meh....you'll never get a satisfactory answer to that one, I'm predicting. It is rooted deep in the self-identity of the particular skeptic, and that is proven to be a no-go zone for most. The same reluctance to examine the evidence on an engaged level is the same thing that drives the aversion to any analysis of why they feel that strongly. I've learned (for me at least) my interest in the question of BF is a nice academic diversion on which my sense of identity doesn't depend. Judging from the positions of some others here, they may be just a tad too invested in this field of inquiry and egos can be rubbed wrong very quickly because of it.
If I had one wish to be granted, it would be that we all try to enjoy ourselves a little more here. This is not life or death as far as I can tell. Sure seems that way at times though, and I don't just mean the skeptics. Of course, if I saw something I couldn't explain, and was greeted with a giant rasberry from others who had never seen such a thing, or would even admit to the possibility/probability of that being true, I might get a little miffed too.
