How do holocaust deniers try to gain followers?

Holocaust deniers have sought out any potential contradictions between eyewitness testimony and the historical record. In one instance, the IHR notes that eyewitnesses claimed bodies at Treblinka were burned to ash, but that partially intact remains have been found amongst the 20-feet of human ash at the site. No attempt is made to address the 20 human ash. correct me if I'm wrong
