It mystifies me why you believe anyone thinks the shooting was justified. Literally NO ONE has said that. Please try to engage with the actual debate instead of making up strawmen to attack.
Yeah, but I don't think that's reasonable to do. If you live in the U.S. you know this is a problem, choosing to still do it is more damning.
I'm not arguing that they should. I'm saying that they are, and having knowledge that they are makes the one calling in the threat seriously in the wrong. I can't stress enough, the caller's twitter handle is SWauTistic. They know full well what they're doing.
