E-Watchman is dangerous in that he hijacks the "awakening" of JW's and leads them into a lifeless limbo where they are no longer JW's and are isolated from their 'brothers and sisters' but are also isolated from everything and everyone else. It's like someone is about to leave the prison of the Watchtower, are at the front gates, but E-Watchman pops up from a trap door and says "Shh, quick, down here, into the Watchtower cellars, we're all hiding in here, all us 'true' JW's. We're hiding from the regular JW's because they're sinful and we're hiding from the entire world because it's sinful. Come and be my follower in this dank empty WT cellar and we'll wait for Jehovah together! Because he's coming very, very, soon."
It's sick.
E-Watchman is just a small-time 'Rutherford', recreating JWism according to his own egotistical fantasies and luring in the unwary.
