I think some of David Icke's stuff is way over the top (such as the reptilian thing you mentioned) however I have to give him credit for inserting the splinter in my mind that JWs is a mind controlled religion. This was quite a few years before I started fading and I had stumbled on one of Icke's books at the library and read through some of it. I had never heard the words "mind controlled" applied to JWs before and I remember when I read it I immediately asked my husband "are we mind controlled? this guy reckons we are" and of course hubby said no we're not (he was an elder then).
But those words, "JWs are mind controlled", stuck in my brain like a splinter and eventually I woke up to the fact that JWs are mind controlled.
So I am grateful to David Icke for that.
