Uh, in reality, those statements ARE being made by a bunch of kooks since there is objectively documented, enormous legal precedent against their inane arguments.
None of these ‘tax protesters’ with their silly ideas win. They aren’t after any grand, righteous, legal principle, they just don’t want to pay what they owe.
If a state legislature thought that it really did not ratify the 16th Amendment, they would have so voted and made it clear. None has done so.
On the other hand, videos like this may enhance business prospects for private lawyers who take on the deluded tax protester’s cases. For money up front, no doubt.
