Newsflash: there is no constitutional way to dismantle NRA, ACLU, NAACP, etc. Get over it.
The NRA must be held responsible for these massacres. An organization that kills or causes the death of children has no right to exist just like the mafia or Al Qaeda has no right to exist.
I fully support the first amendment my friend, it's the second one that needs to be abolished. Our support is growing by the day and I ask every sensible person to join us and make this country safe for our children.
