Stand by your so-called Principle, that it is Theft...refuse to pay Taxes.
I will pick up where you left off in your post: If Taxation is a threat against you, either by the State, or a Person, defend yourself; you are within your Constitutional Right to defend yourself. You have asserted that your life is a stake if you don't pay taxes...defend yourself, Patriot.
If you feel like you're being threatened with your life by not paying Property Taxes for Public Schools, then defend yourself.
If you don't like paying taxes the disassociate yourself from the Fabric of Society, and live as a hermit in the mountains; build yourself a log cabin, don't purchase anything manufactured by Modern Society.--become that Autonomous Man that Walden, and many like him have had wet dreams about becoming...you social creature, you!
