They also tried to do the bump stock thing, which is about the narrowest most useless thing they can do, and THAT went nowhere.
That didn't fall apart due to opposition of the idea. It fell apart because the ban bill had seriously flawed language (in an attempt to ensure that there was no room for similar devices to slip through later on, the definition of a banned device was made broad enough to make reassembling a disassembled firearm illegal), and thus the exact measure was opposed.
And high capacity magazines.
And "assault weapons."
Nobody has explained to me how it's constitutional to ignore half the sentence when interpreting the constitution.
The second amendment clearly only empowers well-regulated militias to have guns.
In the first part, bans on high-capacity magazines and "assault weapons" weren't rejected because the issue wasn't narrow enough. They were rejected because a great many people oppose those specific measures. Indeed, one of the primary reasons so many other bills haven't passed is because that specific measure keeps getting shoved in.
Or, to put it another way:
Group A: "We're getting pizza. I'm thinking anchovies"
Group B: "No, we don't want anchovies"
Group A: "Ok, how about pepperoni, mushroom, and anchovy?"
Group B: "No. Anchovies"
Group A: "Ham, Pineapple, and anchovy?"
Group B: "What part of NO ANCHOVIES did you not understand?"
Group A: "FINE, WE AREN'T GETTING PIZZA AND IT IS YOUR FAULT!"
Regarding the second part, there are two critical flaws with your interpretation.
1.) The only way you could 100% support the "militia only" interpretation is if the "well regulated militia" section was found between "keep and bear arms" and "shall not be infringed." It is possible to state that you believe the "militia only" interpretation to be the intended one, but only if you also acknowledge that it is possible for it to not be. Either it is worded with two possible interpretations, or the only interpretation is the "not militia only" one, just by the way sentence structure works.
2.) The first formal definition of "militia" after the Constitution was ratified spells out "That each and every free able-bodied white male citizen of the respective States, resident therein, who is or shall be of age of eighteen years, and under the age of forty-five years (except as is herein after excepted) shall severally and respectively be enrolled in the militia". In other words, the people who
wrote the 2nd Amendment clearly seemed to consider "militia" to be "any voting citizen that was physically fit for military service."
