If the Dems did manage to raise it to $4k+, many of them would not survive to see the next election. There’s already 90 years of pent up anger over a constitutional right being taxed, then throw in the other egregious tyranny and crimes and lawlessness of the dems and liberals and anti-gun in the just the last 4 years then actually calling for murder of conservatives, then the dems and liberals and anti-gun calling for further imposition of tyranny and marxist socialism – these morons do not realize how precarious their life longevity situation really is – so don’t think people are going to stand for even a further egregious tax on a constitutional right and not take action to dispense with their tyranny.

The fact that the Dems drafted a bill to raise the tax to $4k+ would, IMHO, be additional justification for finding it unconstitutional.

Taxing a Right is unconstitutional. Period, full stop. Just the threat of upping it to $4k per item should give courts pause to say “well, Congress does have the power to tax”. Yeah, except a $1.50 poll tax was deemed unconstitutional. Literacy laws for voting were deemed unconstitutional.
This is why Justice Thomas continually argues [correctly] that 2A is deemed to be [incorrectly] a second class right by many Government and the Courts.
