If the circumstances permit (granted, things would have to get very dire for them to permit), I honestly hope that any and all of those who spewed this intolerable shit and actually materially supported either genocide-party face consequences, akin to how those who supported Nazism after Nazi Germany's fall did in the occupation (well, or were supposed to... the west screwed up the process for west Germany...)

It's not like it would be hard to track them down. Most of these genocidaires are proudly out there showing their asses for this genocide.
