I can only speak for myself. In my case, in a thread like this, what drives me is to help get all the facts out on the table so people can make their own educated decisions.Well said, Mapman. I would add that, IMO, some progress has been made to that end. Facts have been found, experiences have been shared, and experiments have been conducted. For a discussion about a controversial tweak, I would say that this thread is well above average in its substantive content.
As for its non-substantive content, my distinct impression is that the majority of the acrimony has not originated from the Skeptics.
