I'm not quite sure who Lyndon LaRouche Jr. is, even after reading his "About me" page, nor reading about him on Wikipedia.

However, he's had a froth at the mouth about some MMORPG that's just been released (Halo 3), and in the same diatribe attacked WoW,
Entropia, Counterstrike and the like. Apparently they undermine the social fabric of America. Second Life gets a special mention, as a hedonistic and for "the adoption of an arbitrary set of anti-scientific, anti-principled rules, like that of Second Life[.]" Even wikipedia comes in for a swipe or two.

Of course the fact that there are people that use Second Life for education, and there are some excellent science education sites within Second Life doesn't matter. There's no development of the argument that makes it clear how we're all hedonistic and how SL is anti-scientific and anti-principles, but if you enjoy reading rants, you might just enjoy his article. If you don't you might want to be braced in case your boss does when you try to sell him on SL.
