Noone is denying the existence of Germans in Germany. Germans are a product of their current culture.

Ethnocide is describing the erasure of culture, not the organic evolution of it.

I don't wear the same clothes as my grandparents did, I don't eat the same food, don't do the same work, don't have the same social life.

This is my culture, I am a product of it, my grandchildren will have a different culture. It is arrogant to assume my culture is the "peak" of my countries' culture (or "ethnicity"), just as it is not the place of my parents or grandparents to claim as such.

What is propagated here is that Germany (or whatever nation) needs to proactively reject the coexistence of other cultures within its borders for the fear of any kind of impact on itself in the future, taking effort to (depending on the age of who you ask) preserve or reverse its current state. THIS is genocidal language.
