Why would anyone need a 223/556 mm AR-15 assault rifle for home defense? It’s a weapon that can kill someone 500 to 600 yards away and be legally customized with a $150 100-round magazine and a “bump stock” for $369 that simulates automatic fire (about 600 rounds a minute). Of course, the answer is they don’t.
The National Rifle Association ad the Republican Party (people like Texas Gov. Greg Abbott) feed the right-wing militias’ paranoia that they’ll need these weapons of mass destruction for the future war they’ll wage against a repressive government. A weapon that can kill or wound a hundred people in a matter of minutes is a weapon of mass destruction.
AR-15s are WMDs and will cause mass destruction whether they’re used by Republican militias, Islamic jhadists or the mentally ill.
