Superdickery is a humor sight playing on the naivite of old comics panels when taken out of context. It is funny.
Regarding Wertham's book, non-fiction works are still plagued with poor research and opinions masquerading as fact. Take anything from the FOX news line of best selling conspiracy theories and reinterpretations of history. Bill O'Reilly has been on the NYtimes list for ages. Naomi Wolf's recent book has been criticized for doing much the same thing. What about Three Cups of Tea? or any of the amazing diet books or health books based on pseudo-science? What about the books criticizing D&D, articles against Harry Potter, or putting the blame for school massacre's on Marilyn Manson or, more recently, Batman? (The recent Detective Comics story was an interesting reference to this, BTW.) How about the vaccination causes autism myth?
Seduction of the Innocent maybe came from a different era where the public was more gullible, perhaps, but it is only one of many, many examples of fraudulent portrayal of research to prove a point.
