You are totally right. It defnitly is a fundamental right to have the right to belong to a place. I just want to encourage, that nationality is only one part of identity. And even one we can choose not to addvertise, when one does not want to.
I want to emphasize, that nationality is no objective truth. It is a cultural good, that can change. Before 300 years there were no nations on earth. So it is by no way fixed that these institutions will survive for long.
