Any troops forcing entry into homes of US citizens for the express purpose of gun confiscation are not representing the Constitution they swore to uphold and defend and therefore are foreign invaders. Such troops must refuse any unlawful order, whether ordered to fire on their own troops or fire on their own citizens. They must stand down by their own oath.
What about stinger missles? Should citizens be allowed to own these arms?
If you say yes youre kinda crazy. If you say no you belive in 2nd amendment restrictions. Just draw the line in a different place than others.
