So livestock and pets are worth Sandy Hook, Aurora, Parklands, El Paso, Las Vegas, Pulse nightclub, etc etc etc. Etc etc etc etc etc.......
Even though other guns that an untrained 19 year old can't murder 9 people in 30 seconds with, can do that job just as well.
And as fucked up and horrific as your problem with regular mass shootings using semiautos is...........
it's still not NEARLY the deadliest problem with your gun culture.
Why not just concede that there is no rational defence for having your gun laws as they are? That it has been a disaster of an experiment?
