I've read most of this thread and am still a little uncertain as to what you believe
So am I

I have a theory (posted it not long ago) but that's just one possibility.
From my reading of your posts you think:
a) HIV infection is (relatively?) harmless compared to the antiviral drug treatments used to suppress it.
Well, that's one possibility. Maybe I am misled to believe antiretroviral therapy is much more dangerous than it actually is. Maybe I don't even know the half of it. I'm looking for coherence, and saying that "HIV seropositivity is not as bad as the treatment" is coherent with what I believe is reasonable to assume.
b) HIV is rarely (or never?) a significant factor in a HIV+ person's cause of death.
Depends on how you look at it. If you're in Frisco, and you get diagnosed with HIV/AIDS, and put on an antiretroviral therapy, and die within 2 years, does that make HIV seropositivity a significant factor in the cause of death?
Is it possible that HIV is dangerous to one's health, even if only in some instances? I do believe this possibility exists and should be investigated. I'd even ask for a simple quantification: Without antiretroviral treatment etc, is being HIV seropositive more - or less - detrimental to one's health, on average, than smoking? You may be stunned that I dare to ask this, but not even this question can be answered by myself. There has been too much hyperdramatization and doomsaying going on with regards to HIV/AIDS to be able to make any realistic assumptions without the use of carefully designed, double blinded randomized controlled trials.
c) There is a massive conspiracy that has managed to fool (or turn) the vast majority of HIV researchers on the planet.
I don't call it a conspiracy. A conspiracy is when a number of folks sit together and go "How can we fool billions of people"
Let me give you an example, professional race cycling. Everyone's doped there, I think by now people have realized that. But is that now a conspiracy to fool everyone to think the races are legit? I don't think so. It doesn't need a conspiracy to work. Every individual racer has his own, individual motives for doping, and lying about it, and the racing sport removes "bad racers" (who do not dope) on its own. Eventually everyone is doped, all without a conspiracy.
I see something similiar in the medical "establishment" - Too many people's jobs are simply based on the assumption that HIV is a horrible, infectious disease. Even when the science to that end simply isn't there. Every single researcher has his own, individual motive to strongly convince himself that HIV is the most horrible thing since the black death in the middle ages. No need for a conspiracy the way I understand the word.
What evidence would get you to change your opinion?
I don't think "evidence" would help me anymore. Sounds terrible and unscientific, I know, but hear me: I've simply seen too much false, fradulent, irrelevant but important sounding, and doctored "evidence". What I think is needed first, is a massive, public backlash against the AIDS industry, for basically terrorizing an entire generation with lies and exaggerations. Lies about that HIV is an STD, the uselessness of the "AIDS" definition, that HIV/AIDS is a death sentence, and lies about what's going on in africa, or the lies about the supposed effectivity of the antiretroviral treatment. These things are evident, and acknowledged by large parts of the medical establishment, all that's missing is basically the public realizing it.
Once that is done, once it is OK again for real scientists to pose the question: "How dangerous is HIV, after all" or "How would a sensible AIDS definition look like" and perform tests and studies on the subject, then its time to act scientific again.
Right now, if you're a scientist and you'd create a study that could reliably figure out how dangerous HIV natural history is, or if it's more dangerous than smoking, if at all, then you'd get under massive fire from all sides - democrats, religious rights, civil rights, gay groups - because you dare to question the HIV/AIDS validity, because you shame the gay community, because you are obviously racist, etc etc... All sorts of bullpoop things.
There are very many important questions about HIV, about AIDS, but due to the atmosphere, nobody whose job depends on it, is going to ask them or ask them the right way, or dares to come up with the "false" results.
