What If Leftism As Such Is Mass-Murder As An End-In-Itself?

This is left as a question for the bold to ask even of professors in universities. If one is bold and curious as to what the response would be; would they cry McCarthyism, persecution, or invoke nominalism of a most self-contradictory kind, or call the enforcers or what. Warning: trying this could be hazardous to your life-chances. While the hard left indulges a taste for machiavellian discourse, they also know that they depend on a reputation for idealism, in order for the few and unspeakably dirty, to use moral intimidation on their betters.
