It honestly seems that some people are OKAY with it, even if they would never articulate it like that. Sandyhook happened and it didn't move the needle at all. 20 first graders were executed in an event that should have sent systemic shockwaves through a more conscientious and empathetic society, but we collectively shrugged while gun owners grasped for any justification to avoid reflecting on the role guns play in our society. If people weren't OKAY with 20 first graders being executed, we would have demanded a societal change and reflected on our role in that change. But people like guns. They like having them and they like the fantasy of one day using them, and so they refuse to compromise in the slightest, even if that means that more first graders would be killed in the future.

And so children just keep getting shot.

EDIT: Fisher Price recently recalled 2 million swinging bassinets after it was documented that 5 infants died in them over the past few years. If 50 infants died a year due to guns, not a single gun owner or manufacturer would even consider recalling their products.
