Any politician that discusses violence as acceptable can be culpable. Those who said Jan 6th was an act of patriots is saying violence is OK and warranted. That is where this nut got his ideas.what is sick is blaming the gop and conservatives.
Any politician or human who says the violent rioting that happened during BLM protests is OK is culpable for stoking the fires of violence on that side.
In this case it was not all Republicans or all conservatives but those who stoked the fires of a rigged election warranted violence.
