While reading Holocaust articles, I chanced upon this site. Well, I cannot specifically pin point whether it considers Holocaust Revisionism as promoting hate speech. Because if it is established that the site recognises Holocaust Revision as such (promoting hate speech) then the whole complexion into its (EFF) efficacy could be called into question or put in doubt.
Its co-founder's statement in "A Declaration of the Independence of Cyberspace" is indeed impressive.
Since it is long and has an expletive, I have linked it here.
I do not share his design of purpose 100% though,I find it too revolutionary
But the final para,
"We will create a civilization of the Mind (sic) in Cyberspace. May it be more humane and fair than the world your governments have made before"
is a decent pronouncement.
