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.
You’re partially right. I am confusing the two, but not the spirit of their meaning, which is “to conserve”. Conservation is a force for good, but this political party thing is only focused on the bad.
Why let it occupy the entire meaning and overshadow its better uses? To say “Conservative” with disgust is to ignore its potential for better uses.
Why change things when you can argue semantics?
