This was an interesting read. On one hand, it is shocking how the paranoia got out of hand. On the other, however, it is not really that suprising. People have shown fear towards new things throughout history. Radio, television, comics, tabletop RPG's, Internet, video games....you name it, chances are that at least some people though of them in the same negative manner some people thought of D&D.
It is in human nature to fear what we do not understand or is unfamiliar to us and history has a tendecy to repeat itself. So in spite of this experience, I expect specific games will continue to fall under scrunity. In those cases, let us just hope things will work out how they did with D&D....for the best.
Also, it's kind of ironic that this article comes out shortly after the news that Wizards of the Coast are making a kid-friendly tabletop RPG.....or was that intentional?
