Yes, know how you feel. Laurence Gardner is suppressed to some extent by other Grail researchers because of his "monarchist" affiliations. I am grateful for the information he puts out, and try to ignore his political agenda, if there really is one at all.
Gardner comes very close to recognizing the actual identity of Jesus within the family of Herod. But, if one realizes that Jesus and Mary Magdalene were Herodians (along with Peter, Paul, and the other disciples/apostles) and that Christianity was a tool in their play for greater political supremacy, then the Gospels are completely demystified. So, there is a built in barrier for those who want to maintain the sacred aspect of the Gospels and the kingly rights of Jesus and his descendants.
