Dual citizenship

Why is dual citizenship a thing? It makes no sense from any standpoint. Even countries that share a general set of characteristics can and do have competing interests and goals, different political and social cultures etc. Why tolerate split allegiance?

Why do I have to pledge allegiance to any country?

it's the exact point where the question arrises: "What does it mean to be a nation? What does it mean, to be be a citizen of this kind of nation?"

Dude, you will have to read a thousand books to kinda answer theses questions!
or you can shitpost about it on Sup Forums, just stating your opinion and then abandon the thread, the degenerate you are

>"I honestly feel like a global citizen, you know with all the travel and experiences I've had. I just don't understand borders and want diversity"

Did you think the "?s" were rhetorical? I hope to never be that cynical if true.

The Chinese dont allow dual citizens

No one has to pledge allegiance. Other than accident of birth, people generally can consciously choose nations.

I take my insults back. You seem to be a worthy poster.

I would imagine both countries have to agree to the dual citizenship and do some kind of background investigation depending on the history between the two nations.

The only thing that really comes to mind is parents of different nationalities and in that case I think of it as "What religion are we going to raise our kids as?"
