I found a story about the Rabbi's speech in the Virginia Bar Association Journal at http://www.vba.org/mar00.htm
, scroll down to the article "Meeting Close-up: The Dark Side of the Net". Some quotes, but not the transcript, unfortunately.
Rabbi Cooper solemnly pays lip service to free speech by informing us that the best answer to hate speech is more speech, before moving on to tell how the SWC managed to pressure Yahoo into closing 90 "hate sites" - as defined by the SWC, of course. You get the feeling Rabbi Cooper doesn't have a great sense of irony...
I love Goethe's quote from the speech though, it has that sense of inadvertently letting the truth slip out. God forbid people should be able to debate ideas on the web, instead of doing their consumerly duty at Ebay!
