:Re the semi-logic rhetorical speculation on this RfC's launch, this line "Is it safe to say that "Massacre" has fallen out of use in recent years with more current scholarship favoring "massacre"? " has a  very simple answer in WP:TITLE: "the interests of the general readership should be put before those of specialists".  Invoking the WP:Specialist style fallacy to justify an uncalled for reversion of a valid title without knowing anything about the subject or its importance without any regard for COMMONUSE and national standards is getting to be too "typically Wikipedian".  Current scholarship is not the arbiter of things,  though those who invoked it like to pretend it's all that matters...RS is a LOT larger than so-called "scholarship" and its shifting style and methodology stances.
