If someone has already drawn this parallel, I apologize.
There are similarities in this thread to the arguments used to deter various types of lawbreakers, particularly males, who engage in behaviors that run the risk of incarceration, which in turn includes the possible or probable subjection to forced sodomy.
Criminals know whatever behavior they're engaging in is illegal, so they know there are penalties if they get caught. Jailhouse sodomy is unofficially one of those penalties. That's just a fact of common knowledge.
Question: Is a lawbreaker who knowingly risks getting caught deserving of being sodomized if he goes to jail... that is, should he share the blame for getting raped just as he is to blame for going to jail in the first place? Or is he simply taking the risk, and with it the responsibility, for potentially getting raped?
