If you are one of the gun nuts who believes the Second Amendment allows every crackpot to carry a gun anywhere.
As we have seen, Donald Trump and the RNC in general is one of the many groups who want stomp on and burn the constitution. Guns are obviously banned at Trump rallies, and evidently the RNC is going to do the same at the convention. Like student, these bans put them at risk of a terrorist attacks. It is unconscionable, given the assumptions of conservatives, to promote a terrorist attack on the GOP convention by banning guns.
So let us give the GOP what they want, a fully armed convention that is consistent with their core belief in the second amendment. In such a convention, there should be no fear of an external terrorist threat. After all, why would anyone bother with a a suicide vest when the all the artillery needed is right there, thousands of good people with guns ready to defend themselves against each other.
