Your examples are all over forty years old, and all of them put together killed two people (if you don’t count three Weather Undergrounders blowing themselves up by mistake).

On the other hand, this guy in New Zealand killed 50, and the OKC bombing, also by the right, killed 168. These two examples together killed one hundred times as many as yours.

“Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye.”

The violence is on the right and has been for decades now. If you like, I can find dozens of other recent cases of murder and violence from outspokenly far-right individuals, and you’d have a tough time finding two from the left.
