When the Republicans kept trying to repeal Obamacare, they were told it was already the law of the land for several years so they should get over it.
The 2nd Amendment has been the law of the land for far longer.
So you are saying that a piss-poor argument, made by supporters of something that could instead have been supported with a number of strong arguments, constitutes permission to support any old crap with piss poor arguments?
How very...
political of you.
Meanwhile, regardless of how piss poor any argument against the Affordable Care Act might be, in sane person world, you need non-piss poor arguments to support your contention that the second amendment does more good than harm, or should be retained in its present form.
Of course, if you don't have any such arguments, then "Well someone else made a shit argument for something and that thing remains legal" is all you can fall back on. Just don't expect anyone over the age of nine to be swayed by such school yard rhetoric.
"We have had this rule for a long time" is a SHITHOUSE reason to keep a rule.
The second amendment passed its use by date, if not with the establishment of a permanent US Army in the 1790s, then with the widespread adoption of breech-loading firearms, following the 1808 development of the
brass integrated cartridge. Just as the 2nd Amendment does not grant US Citizens the right to bear nuclear weapons, nor does it grant them the right to bear weapons that use another such revolutionary technology never imagined by the framers of the Bill of Rights.
