this is vaguely related to the string theory related post from a day or two ago, it's all bazinga science folks TL;DW string theory is a big thing because people that read pop science really liked it and it took a long time for physicists to come out in force and say "this is untestable garbage"
We like the hanging of Mussolini because it represents the triumph of the Italian public over Mussolini. If the picture was more zoomed it, it would still be more nauseating than anything because it is still fundamentally a mutilated corpse. We may support killing Mussolinis, and we may be flippant or jovial in our talking about supporting killing Mussolinis, but that does not make the actual act of killing a Mussolini fun. Even if the killer is happy in the act, which would be a bit odd, we would expect it to be mainly due to the public good the killing represents rather than the visceral reality of the immediate situation.
I was actually talking about how fascists tend to self-select for enjoyment of murder, especially for murder positions.
