Also, why does federalization have to mean the death of cultures? Can't we come up with ideas how to have both?
Since this has now started to slowly change, it's probably not a very good idea to pay too much attention to what they're culturally pushing anymore.
Anecdotally, English is the only foreign language I know well enough to communicate fluently. Suppose I received a job offer from Germany and decided to migrate. Should I start learning German along with learning at a new job and other obligations, keeping in mind I will probably switch jobs again in a few years? What's next - French or Italian?
Language should serve the people, not the other way around.
I didn't think it was them being stubborn, just me being ignorant, because I don't think I am the center of the universe. Yes, am immigrant to Germany should absolutely learn German. Countries and their people are not the backdrop for someone's main character complex.
