That's fairly close to my impression also, albeit minus the exaggeration. I didn't find much value in anything that was written. I guess it wasn't meant to convert new followers to that line of thinking as much as it was meant to make current followers grab a torch and a pitchfork and fight the establishment.
Probably, but the arguments are pretty well supported text-wise, though I'm sure that it'd be just as easy to find one's own texts to disprove it.
