David Icke has brought forward / provided good commentary on a number of subjects that all needed such help. As such it is difficult for me to deny giving him any credit at all, as he deserves credit for the good he's done. Over the years he's gotten a lot right.
Beyond that, he seems to rely on a little credibility to push a lot of 'stuff'.
Probably a disinfo guy much liek AJ.
With no other source for a given subject, I will not promote it just because he did.
