Yes, the parents. How many gun-owning members of the public without children inside volunteered to go in shooting, since they promised everyone they’d be safer if we kept the dogshit gun laws that armed the murderer in the first place?
The reality is that for all their flowery rhetoeic, gun owners only care about their own self interests. The middle-aged, morbidly obese man who wouldn’t even wear a mask is not going to fight a tyrant for you. He just wanted to keep his toys.
And if they don’t care about people being murdered with legal guns, why should I care about them being murdered because they didn’t have a legal gun?
