Republicans maintain that this Supreme Court is not a bunch of Taliban hacks; supporters say that this court is merely guided by its commitment to Textualism/Originalism.

However, if this is true, then the Supreme Court should have no choice but to vastly limit the reach of the Second Amendment!!

Indeed, the principle of Textualism/Originalism is to say that all laws, including the Constitution can only be interpreted according to the meaning of the words at the time they were written

This absolutely insane view of the law would therefore bind the Supreme Court to the following reasoning:

What we refer today as firearms are, in fact, completely alien to what was understood at the time the Second Amendment was written (1791)!!!
This is primarily due to what we generally refer to as ‘bullets’ today..

Indeed, today’s ‘bullets’ are, in fact, cartridges, or ’rounds’, or shell casings, which, in the words of Wikepidia, 
“[are] a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device (primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting.[3] Although in popular usage the term “bullet” is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile.”

Such devices, however, did not even exist at the time the Second Amendment to the Constitution was written!

Instead, the closest thing to our modern cartridges were paper cartridges, but they were unruly, unreliable, and, most importantly, only allowed for a single shot to be fired, requiring a lengthy reload (and often cleaning)..
The mechanism underlying all modern cartridges in use today was only invented around 1845

This, therefore, means that, according to a Textualist/Originalist reading, not a single type of modern firearm is protected under the Second Amendment!!

No revolvers, no semi-automatic handguns, no long guns, no rifles, no shotguns, not even hunting rifles, or single shot handguns!!

Indeed, in its recent ruling ‘Dobbs v. Jackson Women’s Health Organization’, the high court used the notion of Textualism/Originalism to assert that unenumerated rights cannot be considered.
Moreover, while the high court reaffirmed the right to bear arms’ preeminence over all other possible rights and reason, they also, thereby, unknowingly asserted that the types of arms protected under this amendment can only be seen as those which existed at the time the Second Amendment was written!
