It's your moral duty to avoid paying tax, if you're an American.
It’s a big stretch to assume that the current tax regime is related in any way to the will of the group of people who are currently subjected to it.
By avoiding paying taxes, you first and foremost damage the community you live in.
Of course the legal and ethical way to perform a tax protest is to simply have so little income that you don't owe them a thing
That's the way it works. If you're really wealthy your team of accountants can find all sorts of ways to hide income and reduce it to zero or less. The more money you have coming in the less income you have to report, until the government you bought fair and square ends up owing you. Taxation is wonderful extra teat at which to suckle.
I know it's considered a sport but a moral duty?
