What about all of the other violence I listed? It's orders of magnitude more severe. We don't know the motive of the shooting, but it could very well be someone who's related to the victims of the violence Kirk endorsed.
The main reason is that the side he's on his pretty unhinged and they think it's more important than all the other violence listed.
It's like when a conservative person is canceled they throw an absolute fit, then turn around and cancel someone on the left, without making any connection.
This is the sort of violence that begets more violence.
