Every state DOES have various laws which limit free speech; just try yelling "fire" in a theater and see what happens. Try sending a death threat to your mayor and see what happens.<quoted text>
It is not up to the States to decide. The 2A applies to all states equally, if I could own an AR in Maine, should be able to own one in California, or anywhere in between. The Heller ruling declares the 2A as an individual right, and extents to "common firearms." Is it up to your respective state which amendments apply? What if your state legislators enacted a law that limited free speech, is that up to the state too? This is seriously all about individual freedom; punish criminals and keep weapons away from the insane, not law abiding citizens.
ALL rights can and are limited by the federal govt as well as the states to varying degrees.
Yes, the activist ruling in Heller created a federal individual right where none existed, but since we have a federalist system of government, the states can and do make restrictions on gun rights.
If there is an individual right which can't be infringed, then that has to apply to the insane and criminals as well.
