Sometimes I like to bring up one of the Waco Siege survivors and his account from inside the compound when the ATF was firing on his position from a helicopter. Talk about an oppressive government. Of course most people have only heard one side of that story as perpetrated by the press at behest of the DOJ where it was the Branch Dividians that fired first. (If you ever want to hear the other side you can always try to reach someone who was truly there. He still works and lives in Waco...TreeServiceWaco.com)
But if that doesn't work I like to bring up my first hand knowledge of another time not too long in our past when a few of my other friends absolutely needed their assault rifles. It was the early 90's and it was during the Los Angeles riots.
A couple of my Korean friends who owned shops in LA absolutely needed their assault rifles for several days, not only to protect their property and their livelihoods, but to protect their lives. As they would tell me later it was a war zone!
They were shot at. Had stones, and molotov cocktails thrown at them. Groups were trying to rush at them and drive cars into their stores. They had to create barricades to keep the cars from destroying their storefronts. There were fires raging all around them and they had to help keep the flames away from their building all the while keeping gangs of people from looting their store and rushing their position and killing them.
This went on for days until the National Guard came in to restore order. They were not expecting the riots to happen and they had to make due with what they had on site. Luckily they had enough food and water because they were a convenience store and also they had enough ammo because they had been robbed in the past by some local gangs and the local gangs there always had assault rifles and were known to take revenge on any good citizens sticking up for themselves.
BTW, I am not completely against the government, obviously they saved my friends lives and without them order would not have been restored. I am only against out of control corruption when it happens and violates our rights as citizens. I'm not an advocate for Martial Law but I'm also not naive enough to think that it doesn't have its place. While there will always be some level of danger having the military patrol the streets, it was done the correct way with them eventually leaving and giving back policing duties to the proper authorities.
Of course then you have the handling of Hurricane Katrina with the police going around and trying to disarm the citizens while looters ran a muck and FEMA with held food, water, and medicine. So when the government does a bad job I'm gonna criticize, when they do a good job I'll praise them.
The bottom line though is that when society collapses it is solely up to you to protect your family. Help may not be coming for a very long time and if it does come it might come to disarm you. Be reliant, smart, vigil, and prepared. You have every God given right to protect your life, your property, and your family's future.
