You're right that I didn't write some lengthy dissertation about the nuances of the gun control debate, and I didn't think it was needed. I can certainly counter any point that someone with a different opinion cares to offer with "reasoned argument", in fact it's easy - just about anyone can do that simply because the facts are on our side. So what I did was make a quick statement that, when the complexities of the debate are boiled down, was one hundred percent true. Just because something might be considered a buzzword doesn't necessarily mean it doesn't also have merit. Now normally at this point I would say something like 'can't we just agree to disagree', but since we seem to be pretty much on the same page here, can't we agree to agree?
This is all more reasonable than the they're-all-evil bit, but it's still flawed - there's no 100% solid argument and especially not when it comes to Constitutional interpretation. Understanding both sides and being able to play up and play down particular things is key to changing anyones opinions.
The fact of the matter is that the language of the Second Ammendment can be taken several different ways (is arms modifying militia or are they separate thoughts?) and doubly so if it's viewed through a new historical interpretation (should 'arms' mean assault rifles and F-18s or the flintlock muskets and swords that the framers would have imagined?)
The trick, then, is to make the case for several things: classical conservatism (we've done it this way for 200 years, there's no compelling reason to change), an interpretation of the document as wide-ranging and living (the framers were smart enough to know that arms would come to encompass other things, as evidenced at X, Y and Z points) and the effect a change in interpretation would have on everything else (ie, if 'arms' means swords then musn't man mean white land-owner? and so forth...)
Then you have to downplay the flaws in your argument. If 'arms' can't be limited to swords and flintlocks... then how do you set the standard? Should we all be allowed access to thermonuclear weapons? If militia is the word being modified (and lets face it - comma or not, it is) then how can we define militia in the broadest possible sense?
It's a very nuanced and difficult thing, and the ability of 'our' side to make a proper argument is hurt by all the loud arm-flailing rhetoric. (... note that I'm sure someone with an actual background in constitutional law can come along and say that I'm being far too simplistic...)
Except San Francisco in particular prides itself on being "progressively" anti-establishment. The voters there are not going to throw out a politician for wasting time passing illegal laws as long as those laws make the right PC statement in their eyes, that's exactly what the people there want. A good example of that would be how the 9th Circuit Court of Appeals (based in SF) is the court with the most overturned decisions by higher courts in the entire country. These particular judges are generally known to make their decisions based on their personal opinions rather than case precedent or the letter of the law. Time and time again their rulings are later struck down, but the judges still manage to keep their jobs.
I don't think you're seeing the big picture -- all the San Francisco city councils and the Vermont state legislatures and the liberal-beyond-their-means judges in the country are absolutely necessary to the process. The fact of the matter is that if no one passes these laws in the first place then the process can never move against them.
Every time some city council decides to ban handguns or cheeseburgers then someone ultimately contests it and wins. It forces the people who passed the law to stand behind them and ultimately have them overturned.. and in so doing builds up a big stockpile of legal precedence, which is the most precious thing anyone who wants a basis for a higher court argument can have.
A city council banning cigars as a gimmick for their wine and cheese constituency should be celebrated -- it is the first step on the process that leads to the Supreme Court stating for all time that they can't be banned.
