Jack Thompson is an old-boy lawyer from the sunny state of Florida who got turned down for the senate (or was it that he was in the senate but sucked?)... either way he's the Biggest Douche in the Universe.
He's advocated against the hula hoop, Elvis, comic books, MTV, and now video games. Ass you can see, it's just a generational thing (I said ass, hehe), so whatever the next big entertainment medium may be, someone from his demented corner of the galaxy will be against it.
I'm so glad he doesn't have kids. >_>
