I don’t think that those who have wished such an act be perpetrated on a perpetrator are “advocates” or secret wishers.
It would seem that they are seeking some sort of justice, which seems to be lacking in our “ justice system”
See the Channon Christian and Christopher Newsom murders in Knoxville some years ago. The abject depravity of the acts of the savages who perpetrated this crime screams for capital punishment for anyone who was even remotely involved. Yet only one got the death penalty, and now has a new trial due to the scumbag judge.
I still think equating “justice” with “anal sex” is very strange. I wish for hanging or a firing squad for egregious criminals.
