The tax would already have been paid on

The federal sales tax would have been paid before it existed? "Fair" taxer logic.

Better read that post again. Nowhere did it say "federal sales tax", but merely tax - income tax in the particular case.

One of the precepts of the FairTax as stated in the bill is that a thing would be taxed once and only once.

Typical Squirrel misstatement on your part Mojo.
