The liberals want power, and people in power fear those who have the means to remove their power. An armed citizenry is essential to preventing those in power from abusing it. Liberals want to limit the ability of those to fight back, and here's how they will do it.

As stated, it's practically impossible to go door to door to confiscate firearms. It would cause riots and lead to bloodshed all over, both for those with the guns and for those trying to take them away.

If you can't have an all-at-once confiscation, how to you remove guns?

1. Go after manufacturers and dealers by making it so expensive (either in taxes or red tape or by allowing lawsuits against them for deaths by firearms) to do business that they shut down completely or move out of the US.

2. Ban imports of firearms into the US. This paired with getting manufacturers out of the US means that new guns will be extremely difficult to come by for law-abiding citizens.

3. Ban transfer of firearms from one person to another. This will take care of passing firearms down from parents to children.

These three thing by themselves can reduce legal firearm ownership down to nothing in just one or two generations. But wait, there's more!

4. Ban carrying firearms in public (anywhere not at your own residence). This will mean people will be arrested and guns confiscated when you try to defend yourself away from your home. More guns off the streets.

5. Ban "assault rifles" completely. It was done before, and the definition of "assault rifle" can and will change many times over to include many types of rifles and even hand guns that don't pass a political test (if it has a thing that goes up...)

6. Ban common ammo and heavily tax what remains. California already banned lead ammo for certain big game and it will be illegal to hunt anything in the state with lead by July of 2019. They claimed it was concern for the environment, but whatever. They can use the same or similar arguments to ban lead-based ammo for non hunting firearms, too. They can call it an environmental or health hazard. This will make it nearly impossible to find ammo for your legal firearms, and it will cost an arm and a leg to buy it if you find it.

7. Make stand-your-ground (castle doctrine) illegal. By saying you have to try to run away or do something else before pulling a gun to defend yourself, you can make legal gun owners criminals for trying to defend themselves. Also, removing laws that protect people from civil litigation for legal self defense will prevent people from using guns to defend themselves in their homes.

8. Prevent purchase and ownership of firearms for people on certain lists. The no-fly list was bandied about months ago, but it's a good example of how politics can remove freedoms without due process. The IRS targeted conservative groups with audits and denial of special tax statuses for political reasons, and the same can happen to these "lists" that prevent firearm purchases when there is no due process. Just add a name or a group of names (NRA members might eventually become suspect of domestic terrorism by liberal, so let's just add the membership list to the database of potential terrorist suspects) and make it extremely difficult for them to get their names off the list.

9. Prevent purchase and ownership of firearms for people deemed mentally unfit, and then change the definition of "unfit". Similarly to #8, all they need to do is say that if you've ever been diagnosed with depression in your life, saw a therapist for any reason, took any prescription drugs on a particular list, or hell, if you've ever been arrested for being in a fight or fired for yelling at a coworker, you might show up on a list of mentally unstable individuals who have no right to have a firearm. With mental illness being somewhat fluid and definitions changing so often, it wouldn't be hard to disqualify a substantial part of the US population from owning firearms.

In addition, politicians can require insurance for firearms; make it illegal to carry any firearm across state lines; make owners liable for stolen firearms; and a host of other methods that will incrementally reduce overall gun ownership and make legal gun owners criminals. And all that's needed a liberal majority in the Supreme Court, which will happen if Hillary is elected.
