If there was ever any doubt, the 16th Amendment has now been exposed for the trojan horse which it has always been. It is effectively a gaping breach that was opened in the Constitution which grants Congress virtually unlimited power, under the guise of taxation. It is an open invitation to making We the People abject slaves to our federal government, and it has always represented such a threat.
Accordingly, if the People want to remove this power from the federal government (and we should) then the 16th Amendment MUST be repealed. In the interim, the People should take the initial step of removing from office all those traitors who have dared to blatantly exercise such arbitrary power, starting with the November 2012 elections.
Notwithstanding the ruling, Chief Justice Roberts could have joined Scalia et al to overturn the sloppily written and dishonestly passed ACA, and I believe this is what he should have done. Instead, for whatever reasons, he chose to become activist and rewrite or reinterpret the ACA into a Constitutional format, which was, regrettably, within his judicial purview.
Regardless, it should now be clear to all that the 16th Amendment is entirely incompatible with the concept of limited government, and it always has been. Roberts has simply shrewdly exposed this fact for our edification, and I hope the People are aware enough to vote accordingly in November.
