I am a liberal who supports Bernie Sanders.

I support a right to bear arms (I know, shocking coming from Kentucky).

However, I am personally of the belief that we need to disassociate the gun debate from the second amendment. I feel the ninth amendment makes a far better argument for gun ownership.

We need to reframe the debate of guns from one of liberty to instead a debate of personal freedom from ones rights being infringed.

For example: "I support a right to bear arms, but in my opinion, when you violate the rights of others, you should lose your right to bear arms. A gun in the wrong hands can take innocent lives. Why should we trust peoplehe who have robbed at gunpoint with the right to own a gun? In my opinion, the punishment for violating the rights of others should be the loss of the rights you tried to deprive. Everyone (minus the blind) has the freedom to drive. However, if you get into too many accidents or dangerous situations, then we take that right away to protect the rights of others. The same should apply to guns. Guns are a tool. Useful for hunting, protection, and sport. However, should you use guns to violate the rights of others or to attempt to violate the rights of others, the government should reserve the right to take away your license, so to speak."

With this kind of argument, you can convince far more people. Frame it from their perspective. Conservatives generally agree the government's number one job is to protect people. This is an extension of that.
