Here's a link to the Flying Spaghetti Monster stamp [fsmstamps.com]
It is illegal to write on US paper money or coins .
"Whoever mutilates, cuts, defaces, disfigures, or perforates, or unites or cements together, or does any other thing to any bank bill, draft, note, or other evidence of debt issued by any national banking association, or Federal Reserve bank, or the Federal Reserve System, with intent to render such bank bill, draft, note, or other evidence of debt unfit to be reissued, shall be fined under this title or imprisoned not more than six months, or both."
"Whoever fraudulently alters, defaces, mutilates, impairs, diminishes, falsifies, scales, or lightens any of the coins coined at the mints of the United States, or any foreign coins which are by law made current or are in actual use or circulation as money within the United States; or
Whoever fraudulently possesses, passes, utters, publishes, or sells, or attempts to pass, utter, publish, or sell, or brings into the United States, any such coin, knowing the same to be altered, defaced, mutilated, impaired, diminished, falsified, scaled, or lightened—
Shall be fined under this title or imprisoned not more than five years, or both".
The law against defacing currency only applies when you do so "with intent to render such bank bill... unfit to be reissued" (US Code title 18, pt I, ch 17, s 333). Freedom-stamping only makes sense when you intend for the bill to be reissued and widely circulated. And the spirit of the law really only applies to money you haven't earned (e.g. if the Fed tries to destroy the notes to rid itself of liabilities, or a cash-heavy investor tries to pull a Goldfinger).
Here's the stamp that the Freedom From Religion Foundation sells [shop.ffrf.org]
@SkotlandSkye You can interpret the law any way you want. I did my part in establishing you were aware of it. I won't be needing a stamp. Thanks for the info.
@kensmile4u This is not "my" interpretation...this is the interpretation by many groups including the Freedom From Religion Foundation.
Even if I thought you were right....do you not agree that “One has a moral responsibility to disobey unjust laws” ?? (Dr. M.L.King quote)
“Protest beyond the law is not a departure from democracy; it is absolutely essential to it.”
― Howard Zinn
@SkotlandSkye I do agree that civil disobedience is necessary against the tyranny of christofascists. That's why i said "you can interpret the law any way you want." In other words do your thing but please be careful! I personally choose to work on this issue in different ways.
