<The issue isn't nuttiness in the case of BD it is outright fraud and classic pseudo-scientist techniques. There is nothing nutty about panspermia or the possibility of life on Mars. These are legitimate research subjects followed by many real scientists. See Tom and my listing of pseudo-scientist techniques if you think BD's approach is scientific.
