But really it is there for a REASON. You are a citizen of your state first, and then a citizen of the United States.
Very few people identify this way in the modern age. I've been a citizen of over half a dozen states. I don't even consider it anymore, I move where the jobs are, wherever the jobs are. I am an American first.
Whether or not "people in the modern age" identify or not with their state, it is their state that issues them any of the following: driver's license, state id card, CHL/FOID/etc, and I think also hunting & fishing licenses. So you implicitly are a citizen of [insert name of state] whether or not you consciously acknowledge it.
