Ken McVay, an American resident in Canada, was disturbed by the efforts of organizations like the Simon Wiesenthal Center to suppress the speech of the Holocaust deniers, feeling that it was better to confront them openly than to try to censor them. On the Usenet newsgroup "alt.revisionism" he began a campaign of "truth, fact, and evidence", working with other participants on the newsgroup to uncover factual information about the Holocaust and counter the arguments of the deniers by proving them to be based upon misleading evidence, false statements, and outright lies. He founded the Nizkor Project to expose the activities of the Holocaust deniers, who responded to McVay with personal attacks, slander, and death threats.
