Pretty neat trick there.
Oh I do agree... but not with what you meant.
For one you completely ignore the history of 2nd amendment jurisprudence between the very origin in the late 18th century and the Heller case in the 21st. Eliding 200 years is a neat trick indeed. Considering which years it would be more evident that the common interpretations of the amendment almost from the start were aligned with individual rights, self denfence, and therefore with the Heller ruling. Considering which it would also be obvious the gun control rationales (and rationalizations) started gaining ground well into the 20th century, with Heller being one ruling among others that rather reclaims the historical US tradition against more recent changes.
For another, while focusing on the meaning of arms, you assume a meaning for militia that is normal today and apply it retroactively to the 18th century. Militia just meant armed populace and assumed volunteers, it was not specific to organized state armies, or whatever you'd like to call them.
It sure takes chutzpah to look at the 1780s and 90s context and imagine some 2nd amendment controversy during the ratification debates. As far I know the only substantial disagreement over the 2nd amendment involved the mention of religious persons. Takes even more chutzpah to interpret the text, despite its awkward grammar, to mean almost the complete opposite of what was practiced and culturally normal in the early USA for at least 150 years afterwards.
Neat trick indeed. It's called historical revisionism, and not of the good kind.
