I don't think it really matters what the current definitions are of words found in a 233 year old amendment. What matters is the definition of the words when the amendment was adopted.
In 1791, "militia" meant groups of fighting age / able bodied men who protected their villages / towns / cities, their colonies and ultimately their states. In 1791 it was the responsibility of the states to organize these militias. The other important phrase is "well regulated", back then this did not mean government regulations as we know them today but rather it meant the men were properly organized, sufficiently armed and very importantly, a disciplined fighting force.
As for who would fight if there were a civil war, in the VAST majority of wars it is always a minority of the population who are combatants. I disagree with your assessment of today's climate. Those of us who object to fascism, racism, kleptocracy and totalitarianism do not possess the passivity of the peaceniks and hippies of the 1960s, instead we have the determination of those people who protested and marched against the national injustices and the criminality of politicians in the 1960s. I couldn't care less about Baron and, Newsom doesn't factor into this calculus for me. The rising fascism in this nation is being promoted by the super wealthy as that is who fascism benefits the most.
As for the US losing, Ikeo, we lost the moment we elected a

totalitarian to a second term. As for there being no benefit from fighting, conflict is always the final stage of diplomacy and virtually every shift in human society has been precipitated by conflict and protected via conflict. If human beings as a whole were reasonable and rational, we would not worship invisible friends nor would we elect conmen and traitors to lead our nation but, here we are.
You said: "2A locally and economically globally were in trouble." I absolutely have no idea what that sentence means and hence I cannot comment on the entire paragraph. Please clarify this for me.
You said you don't have an answer. I am not entirely sure what the question is, if it is "how do we keep our nation together?", we do whatever is necessary to neutralize the

s, we once and for all get all of the profit and big / dark money out of our political system. We modify our constitution to severely limit the powers of the presidency and even consider changing our form of government to a parliamentary model with our leader being a prime minister so as to eliminate the possibility of another wanna-be king bull

ting his way into the ultimate global position of power.
