All your link to a single footnote on a Wiki page shows is that some anti-Communist contributer to some anti-Communist book about how the Nazis and the Holocaust were nothing special - disowned and discredited even by its own main authors - claims "between 85 and 100 million" victims of Communism.
Numbers arrived at by including:
1. Forces invading Communist countries
2. Civilians in Communist countries killed by foreign aggressors
3. Anti-Semitic militias who carried out mass murders against Jews
4. Simply adding millions from nowhere (admitted by at least one author of the book)
Nobody in their right mind takes that book seriously; not the authors and not the people who use it to score political points.
