I don't know that people are unwilling to _modify_ it, but rather to _violate_ it. I honestly personally would be pretty happy with no 2A, but unless the specific majorities required for an amendment agree with me, I'm strongly against violating it ad-hoc. The rule of law is simply a lot more important than any given policy.
But we already are and have been for a very long time (the 2A has no limitation as tintypes of arms), and, more importantly, we’re violating the premise it rests on regarding reliance on the citizen militia without which it makes no sense (and we've been doing that for longer.)
I fully agree that the amendment process has to be used. I would be in favor of a 28th amendment placing well thought out limitations on the 1st or the 2nd amendments. Assuming I thought that the limitations it was placing on them were good limitations.
The difference is between broad consensus and divided opinion. A Constitutional amendment requires a 2/3 vote of Congress to propose, and ratification by 3/4 of states (which means any Constitutional amendment would require support from both red and blue states). Ordinary legislation only requires a 50% + 1 majority.
That's not really true of any non-budgetary legislation (for now).
Where that's approximately true, it's actually 50% + ½.
In the Senate, though, in practice, due to cloture, it potentially takes a 3/5 supermajority for most regular legislation.
Yea,that's like... The entire point of the constitution. This is like saying "what's the difference between changing a law or breaking and entering after asking your friend Jeb if it's ok".
