They're not challenging the law. Look at their argument -- they're not saying that it's wrong to levy taxes.
This is precisely what I had in mind when I said you are playing semantic word games. The law is an abstract entity and the tax law is actually a collection of 100s if not 1000s of provisions or mini laws if you will. They said it is wrong to levy taxes on them. They were challenging the provision relevant to them and in this regard there were saying it is wrong to levy taxes as far as they were concerned.
They're saying that the IRS's math is wrong since ordinary labor is not covered under the tax laws.
It could also be construed that they were saying IRS' application of the law is improper.
What is "challenging the law" to you? Refusing to obey a whole book of law which (according to the government) contains a provision that applies to you?
That's not challenging the law --
I believe they are in court because they are in fact challenging the law or more strictly speaking the application of the tax law.
They are in fact taking the position their income cannot be taxed, while certain readings of the law convince many millions of americans it can.
Is that not a challenge?
that's the legal equivalent of saying the government made an error in calculating your tax liability.
It is not the same thing.
Browns did not admit any liability, they did not concede anything to the government and rather took a very hard line position with respect to the tax law.
Of course ultimately they paid a heavy price.
If they were actually convinced that the laws were wrong, they would civilly disobey them -- not play legal games around them.
They did not pay taxes, they refused to be arrested willingly, they refused to appear for trial, they lost much of their assets, they stockpiled many munitions and booby traps.
You do not believe this qualifies as civil disobedience?
You would be hard pressed to find much cooperation from the Browns in this process, in fact I challenge you to find instances of civil obedience.
The Rosa Parks analogy is totally apt here -- these people aren't saying that black people should be able to ride at the front of the bus. They're arguing that it's fine to discriminate against black people -- but they're not black, so telling them to go to the back of the bus is wrong.
With your use of Rosa Parks, you implied that they did not make a big enough deal of the situation, that they should have pronounced the whole tome of tax law null and void.
You imply that this act would be preferable to the narrower road that they took.
I ask you why doing this is somehow preferable, in light of the fact, that the government does in fact have a constitutional power to tax and more often than not when it comes to tax protesters it is simply the way that power is exercised rather than the existence of the power that ruffles their feathers?
Not in a 1000 years you will get a government that will abdicate all powers of taxation, for such a government simply cannot exist.
