So it's your belief that the Founders wanted an inalienable right for street criminals and totally crazy mental patients and mass murderers to own and carry firearms?
Of course they didn't!
I'll tell you what... Since you can't divorce yourself from making irrational, emotional arguments, lets use the same rules of statist policy your proposing to craft another piece of legislation that turns what's now considered a "right" into a privilege:
From now on, women who want to get an abortion must submit for an application to terminate their pregnancy. They will not be able to get an abortion until a government bureaucrat issues the permit and doctors will not perform the procedure without it. The anti-abortionists will be put in charge of the application process and see to it that the applications take 10-12 months to be processed and are only issued after the birth of the child. That should effectively ban abortion through a backdoor effort... they aren't saying you can't have an abortion, so it gets around Roe v Wade, just that you need permission to terminate your pregnancy and its no longer a "right" you can exercise without government approval.
There are roughly one million abortions a year, this measure would save more innocent life than your vain attempt at disarming criminals by turning the law biding citizens right to bear arms into a privilege that would only be bestowed upon those citizens our beneficent, incorruptible government deemed worthy of exercising it.
I see massive potential for abuse with the policy you find reasonable. Imagine this legislation were law when Joe the Plumber came under the immense scrutiny he did, government officials already crossed many lines and broke many rules and laws in order to dig through his personal records to try and destroy him with the public. Such a law as you're proposing chips away at all our rights, not just the second amendment.
Government could punish gun owners who speak out against the government, or whatever administrations in power at the time, by revoking, or refusing to issue, their "license" and confiscating their guns.
Government won't have to pass laws that forbid citizens from speaking out against the government, we'll stay quiet on our own.... Out of fear. Fear of losing whatever "right" that people like you have determined now requires a "license" as permission to exercise that "right". Fear of losing our property. Fear of becoming criminals for wanting to maintain our rights
as rights rather than seeing them reduced to being privileges.
"When the people fear their government, there is tyranny; when the government fears the people, there is liberty." --Thomas Jefferson
The big difference between me and you... I want government to protect our rights, all our rights, that's the whole reason we established our government. You want government to decide which "rights" citizens are entitled to exercise and which citizens are lucky enough, or loyal enough to your ideology, to exercise them and worse yet, you think that's the real purpose and role of government.
