Child molestors (or "chomos" in prison slang) are at the bottom of the prisoner hierarchy, no doubt about that. And sex offenders are murdered in prison at twice the rate of other prisoners but still, the vast majority of them will survive their sentences and are eventually released.
Life for child molesters and rapists in prison is not a happy one but most of them will get through it.
And I have a hunch that it is for worse for white sex offenders than black ones.
I never doubted that. But when they get out, they will have a hard time dealing with endocrine issues, particularly late in life.
