Everyone has a right to freedom of expression  No matter how unpalatable their opinions may be, everyone should have the right to voice them. The very core of a free society is the right to express one’s mind freely, without hindrance from the state. When the state presumes to judge good speech from bad, and to shut off the channel by which the designated bad speech may flow, it abrogates its duty to its citizens. The government does this by presuming to make value judgments on kinds of speech, and thus empowering itself, and not the people, to be the final arbiter of acceptable speech. Such a state of affairs is anathema to the continuation of a free society. [1] With free speech the all sides will get to voice their views and those whose opinions have most evidence will win out so there is no need for censorship as the marketplace of ideas will prevent ideas without sufficient evidence from having an impact. Furthermore, the particular speech in question is extremely fringe, and is for that reason a very unusual one to be seeking to silence. Speech can be legally curtailed only when there is a very real and manifest harm. But that is not the case here, where the participants are few and scattered, and those who would take exception to what the Holocaust deniers have to say can easily opt out online.
