3) No marcher would carry or possess a weapon of any kind or ammo during the march.
Without #3, how do you establish #1?
Also, I know a woman with a felony conviction who remains an NRA member due to her political convictions. Her family has a lot of guns and hunt. Does she march or not?
I trust those interested in marching to relate honestly whether or not they own a gun. The purpose would be to show the demorons what 2-3 million armed Americans look like so only those capable of actually hitting the field if the need arises should march.
