You have a habit of claiming that you "agree to disagree" while continuing to make one last attempt to disprove or refute the opposite point. Which negates the point; it thus comes across as an attempt to get one final word while claiming you want the argument to stop.
Which is nonsense, because your definition of "derailing a thread" is to actually respond to what people are saying. If that annoys you, or anybody else, then too bad.
When you post ANY opinion in a thread, you run the risk that people will challenge it. This should be common sense. A rant thread does not equal hate thread where anyone can just vomit out any words that sound remotely negative about Endwalker (or FFXIV) in general, with no dissension about it whatsoever.
Whatever makes it easier for you, I suppose.
Garleans are racist to an INSANE scale, though. Every city-state in the game has had some history of racism, yes, but the Garleans have an actual goal of cultural genocide across multiple continents. Every racist thing you can blame one single Eorzean city state for (oppressing specific ethnic groups, wiping out an entire city, etc.) Garlean has done to MULTIPLE races or countries.
It's not that I don't think Varis had his reasons. Every villain typically has their reasons. But as you said, he was unhinged. And, likewise, the entire premise of "we need to become one master race to win/survive" is not even remotely entertained as correct or true. The scene basically makes him out to be no different than your typical supremacist/racist dictator. He may BELIEVE he's right, but there's no reason to think he is.
That's still the fault of the story, then. If the story wants them to seem more than cardboard villains, then THE STORY needs to SHOW it. Otherwise, we might as well assume that Venat had better reasons for Sundering, but the story just decided not to show us. In a fictional plot, if the story doesn't show or infer something, then it might as well not exist.
We never really see any of these methods of "stability", though. Since most of the provinces we see onscreen are in active rebellion or oppression. I don't doubt that there were definitely provinces (aside from the Capital) that thrived under Garlemald rule....but they're barely seen or mentioned.
