Denying Holocaust-denier their right to speak is a threat to everyone’s freedom of speech. It is essential in a free society that people be able to express their views without fear of reprisal. As Voltaire said, “I disapprove of what you say, but I will defend to the death your right to say it”. As the facts are against the Holocaust deniers their opponents should have no fear of engaging them in open discussion as they will be able to demonstrate how erroneous their opponents are.
