Gun Control in History: The Leftist Wall

Then:
Wrong class; the people of this class were problematic. They were disarmed as the first step in solving that problem.

Today:
The persistent law-breakers want to disarm the consistently law-abiding, "for the sake of the children in the FREE-FIRE ZONES" which were created by the persistent law-breakers, and which accommodate persistent law-breakers with weapons. The law-abiding are problematic because they actually believe that individual inviolable rights under the US Constitution is consistent law. The persistent law-breakers know different, that rights are dispensed to classes by the progressive government as is seen fit, and may be modified or terminated as the progressive government sees fit. These rights include individual's free speech, freedom of assembly, freedom of religion, right to own and bear unspecified arms to protect self, family, community, and nation against malefactors, domestic and foreign.

The persistent law-breakers do not believe in inviolable individual rights, family, deity, national boundaries, or laws in general (except for control of the herd).

Control of the herd under progressive governments has always involved walls:

Buy more ammo.

Or face the wall.
