Saying that nobody can discuss something until there is proof is a sure way of starting another HIV outbreak. Your attitude is exactly the one that got Tricia Deveraux and others HIV+.

Prior to Marc Wallice being unmasked there were rumors about him but nothing definitive. What shut Marc down was not sweeping the rumors under the rug but rather Luke Ford (yes, he deserves almost sole credit), who posted stories everywhere and wouldn't quit until Patrick Collins was forced to make Marc take an honest test. And Lo, that ended a string of HIV infections that had gone on for a year.

At the point of time of the ADT posts you already had industry participants on record on the issue in addition to whatever Luke posted: why not encourage other talent to ask questions? Isabel Ice is not well served by being told "nothing to see here; move along". You would be doing Isabel a favor to leave the thread open and asking "Orange Paddy" to carefully explain how the risks affect her, and suggesting that Isabel call or email friends to see what's up. Few seem to understand the parameters of the medical risks the talent take; situations like this are an opportunity to clear up those issues.

Ignorance is not bliss here, and prohibiting discussion on these thing falls firmly in the “encouraging ignorance” category.
