== Terminology section == 

 The section mixes two things: the discussion of the "mass killing" term in general, and the terminology used to describes the crimes committed by Communist regimes. These two things should be separated from each other. It would be better to split the section on two subsections. First subsection should discuss the mass killing, "democide", "genocide" (both sensu stricto and sensu lato), whereas the cesond one should be devoted to how this terminology can be applied to Communist mass killings.
