I think they actually convince themselves of the crap they write. And you wonder why the "collective" IQ keeps dropping yet they believe they are the intelligent ones.
Small correction. The collective IQ is actually rising. The guys at the top are not getting any smarter but the guys at the bottom are gaining IQ points at the rate of about 10-20 points every 30 years.
It's called the Flynn Effect after the guy that discovered it.
