HIV is not passed on by promiscuity. It is passed on by someone who has it to someone who hasn't. Moralising at people who have "multiple sexual partners" or who are "promiscuous" is neither helpful nor accurate. The behaviours you criticise have been going on for millennia, and not just in third-world countries either, yet AIDS has been with us for just thirty years or so. Using AIDS to condemn behaviour you apparently disapprove of is just wrong.

What was happening with the RC priests was simple homosexual assault.

You are nit-picking. The majoriy of children who were sexually assaulted by priests were just that - children, minors, under-age, call them what you will. 12, 13, 14 years old and assaulted by people in powerful positions of trust. How you can possibly refer to that as "simple homosexual assault", as if it had happened between pissed blokes outside a gay bar on a Saturday night, is utterly beyond me.
