This retired science bod refuses to remain silent, and will NOT be shut up by yours or anyone else’s ill-informed put-downs..

That is his right: to refuse to remain silent. But he will not get to continue his cruel attacks on others within this blog. Positive contributions in science, history or philosophy that pertain to the subject of a posting are welcome. For the time being, however, Colin’s comments will be reviewed by me before being posted. If necessary I may edit or reject what he submits.

The number of complaints I have received is sufficient reason for me to take this action with Colin’s comments. I have no issue with his skepticism or his worldview. We need that here. But we don’t need unwarranted, mean personal attacks on others. Such comments are a thing of the past in this blog.
