"What specifically makes it obvious?"
Jeez, where to start....
Well, lets start with the obvious...
Why would the author demand anonymity, while at the same time explicitly detailing their past?
Or this one:
"I joined all the progressive campus groups....Hermaphrodites are People Too, Black Hermaphrodites..."
There are of course, no such groups.
"I talked my way into several gangs in Chicago’s Lower West Side"
"It turns out that Chelsea is not her and Bill’s daughter at all—but the product of a night of passion between Hillary and the late PLO chairman Yasser Arafat"
Did you even read that stupid sh|t?
