Governments should not allow forums for hate speech to flourish  Denial of the Holocaust is fundamentally hate speech. It is the duty of the government to deny these offensive beliefs a platform of any kind. [1] By blocking these sites, the government denies a certain freedom of speech, but it is a necessarily harmful form of speech that has no value in the market place of ideas. Many people, often Jews, but also members of other discriminated against minorities like Roma, suffer directly from the speech, feeling not only offended, but physically threatened by such denials. Holocaust denial however goes beyond hate speech because it is not only offensive but factually wrong. The attempt to rewrite history and to sow lies causes a threat to the truth and an ability to co-opt the participation of gullible individuals to their cause that mere insults and demagoguery could not. It represents a threat to education by undermining the value of facts and evidence. For this reason, there is essentially no real loss of valuable speech in censoring the sites denying the Holocaust.  [1] Lipstadt, Deborah.
