You're not getting it. You're missing the point. The Democrats know full well that limiting magazine size and banning this or that category of firearms isn't going to change anything regarding public safety. They're not stupid. Just evil.
The whole point of any gun control law is maintaining the pressure of incrementalism. How many times do I have to make the point that when dealing with liberals, nothing is as it appears? There is always, ALWAYS a nefarious goal or objective buried in the fog of concern for the public interest. To understand a Democrat's true intention, don't follow the money - don't follow the hype - follow the POWER. Find the part of any bill that gives the government authority it didn't have before, and THAT'S what it's really all about. The rest is smokescreen.
Nobody except Democrats knew that Medicare and Medicaid were just incremental steps to Obamacare, which itself is an incremental step towards single-payer healthcare. Only Democrats knew that Social Security, originally touted as nothing more than a supplement to your own savings, would become the budget-devouring tax and spend monster it is today. Only Democrats knew that welfare and unemployment insurance, once offered as short-term assistance for a temporary problem, would morph into an instrument of permanent dependency.
And Democrats know that the eventual intent of small scale and arguably ineffective gun controls is the total disarmament of the American people. And you thought the new gun control law was about assault weapons and magazines? WAKE UP. It's about closing the so-called gun-show loophole. It's really about the complete takeover by the government of the sale and transfer of firearms, removing the process completely from the private sector. Nobody will be able to buy or sell guns (and soon ammo as well) without the 'mark of the beast' - the approval of the NICS. Under government control, watch the number of people allowed to complete a purchase or transfer of a firearm or ammunition to shrink and shrink.
WATCH and learn how this is going to be done. The process starts out with Democrats asking Americans to give up the sun, moon and stars of the 2nd Amendment, knowing full well that they'll trade their ridiculous initial demands for a seemingly limited and innocuous compromise. They are fully prepared to give up on banning magazines and assault weapons if they can just get federal control of the entire firearms market, which universal background checks will give them. The Democrats will achieve 2 goals with just that concession. First they get more power, and second, they get to blame Republicans for endangering society, giving them future ownership of the issue. If the Republicans cave and give them a ban as well as control of the market, Democratic Party policy wonks will have won the political lottery and be reduced to giggling disbelief at their good fortune.
