I think Jay Parker is the real deal. There's a point in this presentation where he begins to get angry and starts ranting at the aim low management.
Like I say, I've always known the bloodlines are important but now I embrace this group as above any other, though there may be new less recognizable groups that have as much or more power. All the books in this presentation are well worth making a note of as they will inform the interested student where to corroborate much of his information.
