You signed a petition that called for your state to secede from the United States?
You asked to be removed as a United States Citizen?
And you think that would make no difference in a process where your loyalty to the United States was being assessed?
You have every right to ask to have your citizenship revoked, which is what secession is, a group revocation of citizenship.
But actions have consequences, and asking to be treated as a foreigner might well cause you to be treated as if that is what you wanted.
If you actually want to renounce your citizenship, don’t be surprised if people take you seriously.
If you actually DON’T want to renounce your citizenship, and instead are trying to “send a message”, I suggest you find a way to do so that doesn’t call your loyalty to the country into question.
My guess is you don’t want to secede, you want to fix the country. But if so, don’t sign a petition saying you want to quit.
I am certianly glad that the signers of the Declaration of Independance didn't have your attitude. No I am not comparing myself to them. What happens to me is far less important than the liberty of the next generations.
