The Rise of Right-Wing Political Violence

In 1930s Spain, political violence was the new norm. In America today, a do-sing killing black church parishioners in 2015 or last month's killing of mosque worshipers in New Zealand is not totally implausible that they are right-wing. But Hodgkinson was part of the ecosystem of the left and the right-wing killers were not part of thecosystem of the right. Such killers being part of the left ecosystem is a necessary consequence of the mandatory left principle that there are no enemies to the left. You cannot plausibly maintain both that principle and that you are not responsible for fringe actions.
