There is no way that is parody.
Okay, I'll take that back. What I should have said is that there is no way that was intended as parody.
It's just so over the top fundy that it calls CS Lewis a satanic heretic, calls the pope the vicar of hell, lambasts the "new world order", raves against alcohol, disney, public schools. Goes without saying that it's antievolution as well.
That might make it unintended parody.

David J. Stewart Exposed!David J. Stewart is NOT the way to Heaven!!!David J. Stewart Indicted for Sex with MinorNIV EXPOSED! (by David J. Stewart) (a youtube video, with links to many similar videos).
I concur that this is parody, though unintended parody.
