Those lines are nice and pretty but not reality. Many amendments in the Bill of Rights have been routed through the 14th to apply to the states but the 2nd amendment is not one of them.
The 14th Amendment is (in addition to being a complete fraud, although that is a topic for another day) completely unnecessary with respect to the federal constitution being applicable to the states. To follow your convoluted logic, that would mean that nothing in the US Constitution applied to the states until after the Civil War. That is clearly absurd, and US Supreme Court rulings prior to the Civil War demonstrate that was not the case.
Even if your argument regarding the 14th Amendment were correct, which it is not, the state constitution itself states, in no uncertain terms, that the "right
of the individual citizen
arms in defense of himself, or the state, shall not be impaired
." The only authorized exception, allowing government regulation, is the employment of an armed body of men by a private individual, organization, or corporation. Compare this to the Louisiana constitution's RKBA section, which reads, "The right of each citizen to keep and bear arms shall not be abridged, but this provision shall not prevent the passage of laws to prohibit the carrying of weapons concealed on the person
." In Louisiana, the state regulation of concealed carry is explicitly authorized by the constitution. This is not the case in Washington, where both the federal and state constitutions authorize the individual right to bear arms with no exceptions for mode of carry.
In light of all of this, please explain the relevance of your original comment, to wit:
"But we have to live with the fact that the US Constitution does not apply to the states in this case...Only our state constitution does."
You're kidding about the WA constitution right? You must have a CPL to CC in WA or have a loaded weapon in or ona motor vehicle, period.
Just because something is law does not mean that it is constitutional. I would hope that, like mine, your goals include the eventual repeal of all unconstitutional laws regarding the exercise of natural rights. The recent passage of "constitutional carry" in Arizona (no permit required for open or concealed carry, in accordance with the federal and state constitutions) shows that it is possible.
