Go back and re-read Heller. Look at the twisted, convoluted decisions that SCOTUS has rendered in the past with regard to firearm rights.
Liberals do not care if they open the door to poll taxes. In fact, they may see those as the means to fight Voter ID.
Deceit and fraud are not outside the scope of liberals, even those on the SCOTUS.
Nonetheless, Heller passed, and the dissents agreed with the core point. The ancillary contortions were to avoid explosive tangential consequences, and will not stand up to direct scrutiny.
Other past SCOTUS decisions were more right than many give credit; it was the subsequent interpretation and spin which rendered the environment we are in. (Miller was correct, but ours bought into the spin rather than holding to the actual decision.)
There comes a point where deceit and fraud consume themselves and cannot overcome plain truth.
BCR & I are well aware of your points. We are, nonetheless, optimistic.
