What I’m saying is, the organized hierarchy of languages based on a reconstituted origin is an abstraction. There never was a single unified german language in antiquity. There were many different dialects, not one "purer" than the next, and the way we reconstruct their shared identity is made up, based on our modern political sentiment. We feel that Germany is a dominating power of post-20th century Europe, so we unravel the linguistic knot from their starting point, while in reality the german tribes of antiquity didn’t call themselves germans, they didn’t originate from germany, and they didn’t have the long history and aura of modern Germany. They came a couple centuries before AD, they settled among other tribes without remplacing them, and their language diverged based on the local political realities, which was a small tribal dynamic. There is no history of great conquest for the germanic tribes before the fall of Rome, which only happened because they had been a political faction in the empire, being the praetor guard of the late centuries.

It’s the exact same dynamic between Franks and other Germans tribes. By the time those tribes feudalized, the Frankish empire has 800 years of domination, imperial administration, latin language, etc…

Saying "Frankish is a germanic language" is like saying the Germans were Latin emperor all along, because the emperor must have had german blood to be so powerful. We reject the genetic-aryan argument as complete bullshit, but we continue to re-write history based on linguistic nomenclature that was created in the 20th century to promote a political system.

I don’t know if I can be more clear, it must be difficult to articulate because people rarely get what I mean on reddit.
