I think Jesus would condemn the violence advocated by both Mandela and our perverted military-industrial-complex neocon agenda. Communism seems wonderful if your only alternative is faux capitalism, faux free markets, faux individual liberty as currently exists in our post- constitutional, post-republic, fascist USSA.
Unjust violence as promoted by both the left and right is wrong and needs to be condemned. Think of compulsory government "education," taxation, businesses, international aid, the list is nearly endless – all regulated by the lethal government gun. Until most conservatives/Republicans embrace the nonviolence of libertarianism, I don't have too much respect for them.
