The short answer is yes. But, I am open to the possibility that these tax protestors are techinically correct, but that it doesn't matter because all of their arguments have been struck down by the courts. In the US, courts essentially have lawmaking power by their rulings, and if the original IRS laws did not require certain taxes, the courts have interpreted that they do.
The idea that there is no legal basis for citizens to pay income tax is a scam. End of story.
Believing that you don’t have to pay income tax is up there with believing that the moon landings were done on a sound stage or that President Bush was behind 9/11 or believing that the Constitution has a right to abortion somewhere in the text.
The last one is the trick right? Because the asshats at NOW/PP got a fake anti-life amendment put in, the tax people think they can get teh 16th taken out.
