Evidence and respect in historical debate

Alex Clarke draws a firm boundary against Holocaust denial, grounded partly in testimony from relatives involved in liberating camps. He separates documented falsehood from comparative historical debate that can be pursued in an appropriate setting. Participants should remain polite because people who feel respected are more willing to share evidence and listen in return. His classroom rule treats sincere questions as opportunities to learn and removes personal insults from discussion. Documented claims require evidentiary standing, while difficult questions can still be examined without attacking the person asking them.
