Oh hey, look at that! More ad hominem attacks and doubt being misinterpreted as dismissal of canon! Niiiiice.
You don't declare your own righteousness, especially after dismissing everyone else as self-righteous. To do so is the epitome of arrogance and hypocrisy. History will vindicate you, or it will not.
"[O]verly emotional biased arguments that are largely based around flawed concepts of modern day morality being applied to a fictional setting."
-You've constructed a narrative that paints Garlemald as a victim when in reality they've been victimizing everyone around them for roughly half a century. There is no fact that justifies their actions - you excuse them by constantly citing how they were pushed around before developing their magitek and using tu quoque fallacies to deflect attention away from their atrocities. The Garleans have more than made up for being pushed around, and Limsa's (etc.) transgressions don't subtract from their own - address the criticism levied at Garlemald instead of criticizing others in turn, please. As far as I can tell this fictional setting also runs on a largely modern sense of morality - the only exception is that prostitution is not entirely frowned upon.
Everyone is biased, as well. Not acknowledging one's own demonstrates a thorough lack of self-awareness.
Everyone is throwing spin on the Empire. Everyone is conjecturing and speculating. (No guarantees of a Larsa analogue, yet it's been declared a certainty!) Everyone has subjective interpretations. That said the game itself, by and large, paints Garlemald's philosophy and actions in a very negative light. That may change, but there is no guarantee it will.
Yes, even despite Regula being a decent person and besties with Varis.
(Also Ala Mhigo was completed in 6AE 1335. The Garleans were pushed from southern to northern Ilsabard circa 6AE 800. There is almost literally no way any Eorzean nation could be responsible... and yet... apparently it's acceptable for Garlemald to invade and conquer and call us savages. Huh.)
Final note: YES, I FINALLY GOT THE MAGITEK PREDATOR! It actually does exist and it flies using rocket engines! So worth the effort...
