The most famous forms of Holocaust denial and revisionism tend to focus on Jews, casting doubt, for example, on how many were exterminated in the camps. But denying the impact the Nazis had on the other groups they targeted, including queer and trans people, disabled people and Romani people, is still Holocaust denial. Maybe someone should tell J.K. Rowling.
Fair enough. If politically conservative people legislated with a moderate, cautious demeanor, I would respect that. In fact, I might even side with them on several policies.
