That's a long way to go just to confirm the unlying allegorical causation of genocidal mass-murder and its commemoration. Artists, poets, and writers can treat things pretty much however they want under the blanket of poetic license -doesn't make it true/accurate. I mean... when one is writing fiction about fiction...
Speaking of which, there was no promise not cull humanity again, just a promise not to do so by drowning... apparently I was mistaken in assuming including the phrase "the same way" would serve as a research-inductive goad. Oh well -if you're going to engage on a topic, know the source material. And if you don't, well... you're currently experiencing the consequence. Huh... feels like we've been here before...
Oh, nope, that's just resonant backflow from the next bit --(re: individuals not understanding the words they use) you really should look up "Cultural Marxism" before deploying the term again... or, at the very least, don't capitalize "cultural".
