They’re not so stupid as to do door-to-door confiscation. The Left is good at working around such direct action.
There could be a national uprising if Hillary says “Mr. & Mrs. America. turn ‘em all in!”
Or little baby steps: demonize owners of semi-autos as dangerous racist OFWG’s. Shun gun owners. Government snitch hotlines. Write down license plate numbers.
Meanwhile, those evil gun manufacturers can’t make AR-15’s fast enough.
