Originalism means that the constitution is interpreted using the meanings as it was understood when it was written. For example, if the word "gay" were used, it would represent the meaning contemporary with the Bill of Rights of "happy", not the modern meaning of "homosexual". You have tried and failed to twist Heller to mean "only technology of the 18th century is protected" and to blame Heller on "originalist judges". Both are false.
I gave you a crystal clear Supreme Court quote from Heller. If that's not enough, I'll give you another Supreme Court quote, this one from Caetano v Massachusetts. In this case the Massachusetts State Supreme Court upheld Caetano's conviction for owning a stun gun because they “were not in common use at the time of the Second Amendment’s enactment,”
This argument was unanimously rejected by SCOTUS, including such "right wing originalists" as Stephen Breyer, Elena Kagen, Sonia Sotomayor and Ruth Bader Ginsburg.
We found the argument “that only those arms in existence in the 18th century are protected by the Second Amendment” not merely wrong, but “bordering on the frivolous.” Instead, we held that “the Second Amendment extends, prima facie, to all instruments that constitute bearable arms, even those that were not in existence at the time of the founding.” Ibid. (emphasis added by Justice Alito). It is hard to imagine language speaking more directly to the point. Caetano, Justice Alito's concurrence.
So that should be proof enough for anyone with an IQ over room temperature or even a scrap of intellectual honesty that the Second Amendment does NOT only apply to muskets. The question is whether you fall into either category.
You're the one who thinks the second amendment somehow operates completely differently than the other amendments. Or at least you would be if you could only work up the courage to answer the question that you've repeatedly ignored:
If the second amendment only protects muskets, does the first amendment only protect documents written with a quill pen?
