Repealing it is the only legitimate, Constitutional gun control tactic that the Statists should employ. If successful, the response would be a nice armed Revolution. So I think that it changes a lot, if the Statists have the balls.
Actually, c'mon, let's be real. And I mean "really REAL", cuz we (and THEY) all know exactly how it would go down..
The "response", at least generally,
the would be to log on to NES (and the thousands of other chat forums like this nationwide), screaming WTF! WTF!!.. THIS IS NOT WHAT THE FOUNDING FATHERS.. (etc etc etc)", and screaming "EAT A BIG OLD _**_ MAURA!!".. followed by rallies where a few hundred (out of the thousands of) like-minded gun owners get together and look like a Klan meeting or a gathering of Larry the Cable Guy clones. There be ranting, screaming, largely-ignored requests for press coverage, and, in the end? Everyone would go home all revved-up, psyched up, pumped up, and loaded up for the "revolution"...
Couple of weeks later, right around dinner time with your wife and kids around their law-abiding hubby/daddy, the doorbell would ring...Three or five of the "Sorry, just following orders, Tom" .gov agents/officers (one of whom you recognize from high school or whatever) excuse themselves for interrupting your afternoon/evening at home...
Your acquaintance, who now resembles RoboCop, and the other members of the Reichstag apologize to your wife as the paid thugs (two in full ballistic gear, trigger finger resting in "safe but ready" position) hand you a confiscation order to relieve you of your primary means of self-defense, and primary means of protection from the government tyranny that you're presently experiencing, now in your basement, the garage, your bedroom closet, etc..
You WANT to explode and grab the Mossberg and order the Redcoats /Nazi squad off of your property, but, alas, like millions of other peaceful law abiders, you "do the right thing" in front of your kids.
Then you hop the MBTA to go to work the next morning, unarmed except for a folding knife or next-to-be-banned Pepper Spray and you ride the train into a sh*tty side of town, hoping you make it home tonight without getting mugged/attacked/stabbed/shot/beaten to death etc etc... so that you can have dinner again with family.. and log on to NES and scream with rage. EABOD G*DDAMNED ANTIGUN YUPPIE FAIRIES AND... AND... AND WE'RE GONNA HAVE A REVOLUTION! YOU'LL SEE!! "
That's what the "response" would be, what REALLY would happen, and most people here know damned well that's the truth...And "THEY" (the pink hat twit statist fairies and "smahter than you!" Bloomsuck arseholes) know damned DAMNED well that this is what REALLY would, unfortunately, "happen" in response to confiscation. Think about it. Cuz anyone who believes otherwise is basically "touching themselves" in fantasy.
Just sayin'
