How large scale was the armed invasion of 9/11? 19 men with airplanes killed over 3000 Americans. What do you call the hispanic street-gangs in the Southwest but armed 5th-columnists whose first loyalty is certainly not to the US. How large scale do you need? Do you think we only respond to invasions if they are large enough?
Invaders have arrived in our country with their first act as one of disdain for our laws. Open your eyes for soon the evidence of a large-scale armed invasion will be evident to even you. I say citizens have the right and responsibility to shoot invaders. It is one of the purposes of the 2nd amendment.
