Well, I don't really know how to help you out of your predicament. From what I comprehend, You've already agreed to be liable, and assessed, for taxes. And by filing a 1040, as a "US citizen", you've pretty much agreed with whatever they want to do.
Maybe someone with a cure for this will see this thread and help out. Keep asking around. You never know, there might be a fix out there somewhere.
What you've agreed on, were you AWARE of you was aggreeing on something in the first place ?, did ANYONE explained you what you were doing ?, have you received a FULL DISCLOSURE of ANY contract you have may entered in ?, did you know the government CREATED a person for you ?, did you know that when, you APPLIED for your SSN, in fact, you were applying for a JOB with the government ?, do you know that the ONLY way to pay income taxes is to work for the Government ?, Do you work for the government ?, ...etc...etc....good luck ! :D
Nice Sunday morning listen, Pete Daoust, while I watch the water slowly receding here on Calgary. I found this one interesting as well. https://www.youtube.com/watch?v=OfL9wn6jDgU&feature=endscreen&NR=1
